The Secrets of Story Structure, Pt. 9: The Third Act

The third act is the moment we’ve all been waiting for—readers, writers, and characters alike. This final section of the story is the point. It’s what we’ve been building up to all this time. If the first and second acts were engaging and aesthetic labyrinths, the third act is where X marks the spot. We’ve found the treasure. Now it’s time to start digging.

Like all the other acts, the third act opens with a bang, but unlike the other acts, it never lets up. From the 75% mark on, the characters and the readers alike are in for a wild ride. All the threads we’ve been weaving up to this point must now be artfully tied together. The main character must finally face (and presumably overcome) the antagonistic force by way of first learning from and then overcoming his own internal conflict. By the time the third act is finished, all the salient questions must be answered, the conflict resolved one way or another, and the reader left with a feeling of satisfaction.

It’s a Wonderful Life (1947), Liberty Films.

Because the third act is made up of several important and intricate parts, I’ll be splitting it into three sections, which we’ll discuss in three posts. Today, let’s look at the third act as a whole and, specifically, the plot point that marks its beginning.

What is the third act?

The third act is a place of no escape for the protagonist. He’s been backed up to a wall. He no longer has any options but to face the antagonistic force. All his reactions and actions in the previous acts have led him to a point from which he must face every last one of his weaknesses and mistakes. If he’s to triumph, he must allow himself to be broken by them—and then rise from his ashes with new wisdom and strength. This is do-or-die territory. When he makes his last bid to obtain his story-long goal and his deepest inner need (which may or may not be the same thing, and, indeed, may even be antithetical), he’s putting all his cards on the table. If he doesn’t win now, he never will. That, of course, means the stakes have to be ratcheted to the breaking point. The third act is all about raising those stakes.

The third act will begin with another life-changing plot point. This plot point, more than any of those that have preceded it, will set the protagonist’s feet on the path toward the final conflict in the climax. From here on in, your clattering dominoes form a straight line as your protagonist hurtles toward his inevitable clash with the antagonistic force. The third act, as a whole, is full of big and important scenes, so by comparison its opening plot point is often less defined than the plot points that marked the first and second acts. However, its thrust must be just adamant.

In Christopher Nolan’s Batman Begins, the third act is launched when Ra’s Al Ghul announces his intentions to destroy Gotham, then burns Bruce Wayne’s mansion and leaves him for dead. In The Hunger Games by Suzanne Collins, the third act’s opening plot point is the announcement that, for the first time in history, two contestants can win if they’re both from the same district, which then prompts Katniss to find Peeta. In True Grit by Charles Portis, the third act revolves around Mattie’s discovery of the murderer Tom Chaney and her subsequent capture by Ned Pepper’s gang of outlaws.

Where does the third act belong?

The third act occupies the final third of the book, beginning around or slightly before the 75% mark and continuing until the end. This is a relatively small portion of the book, particularly when you think about all that must be accomplished within it. One of the reasons the third act picks up the pace compared to the previous acts is the simple necessity of cramming in everything that needs to be addressed before the book runs out of time and space.

All the characters (and other important playing pieces, à la the Maltese Falcon) must be assembled. Subplots must be satisfactorily tied off. Foreshadowing must be fulfilled. Both the hero and the antagonist (if there is one) must have time to put into play the final aspects of their plans. The hero must face his inner demons and complete his character arc, most likely in concert with the final deciding conflict between the hero and the antagonistic force. And then everything must be tied off in a satisfying denouement. That’s a lot to accomplish in a mere 25% of the book, so there’s no time to waste. In the third act, we can see one of the primary benefits of structure: for the story to work, all the pieces in the first and second acts must be properly in place to lay the necessary foundation for the finale.

Lessons from film and literature

The third act is where the masters rise above the mediocre, and we can see this nowhere more clearly than in the stories that have wowed us with their endings. Our four exemplary books and movies definitely qualify.

Pride & Prejudice by Jane Austen (1813): The third act opens with the dramatic discovery of Lydia’s elopement with Mr. Wickham. As with the previous major plot points at the 25% and 50% marks, this one is a game changer. The Bennets’ lives will never be the same, not only personally with their loss of and worry for their youngest member, but also publicly since Lydia’s scandalous behavior will almost certainly ruin the other sisters’ ability to marry well. Even more importantly to Lizzy, she fears that Darcy’s abrupt behavior toward her after he hears the news is an indication she’s lost, once and for all, any chance she had of regaining his love. As a woman in early 19th century England, Lizzy isn’t capable of taking direct action to personally rectify the situation. But she does what she can by immediately leaving Lambton with her aunt and uncle and returning home to her stricken family.

It’s a Wonderful Life directed by Frank Capra (1947): The second act ends with Uncle Billy’s losing the Building & Loan’s $8,000 and George’s frantic attempts to recover it. In most stories that plot point would be more than dramatic enough to open the third act. But in this classic film, the third act opens with an even stronger change of events: the appearance of the angel Clarence, who was foreshadowed in the opening, and his granting of George’s wish to “never be born.” The third act is made up almost entirely of Clarence’s action and George’s reactions. The antagonist isn’t even present in the unborn sequence that fills up most of the third act (although his presence looms large). The focus here is entirely on George’s inner journey and transformation.

Ender’s Game by Orson Scott Card (1977): When Ender is forced into the lethal confrontation with Bonzo, he is also forced to the breaking point. The time has come for Ender to leave Battle School and step up to command Dragon Army in a larger arena. But after Bonzo’s death, the commanders realize they’re on the brink of losing the boy they’ve spent so much time and effort grooming to save the world from the Formic aliens. Ender is given permission to return to Earth to visit his beloved sister Valentine. While there, he must make the decision that will change not only the fate of the world, but also his own life. From the moment he decides to move forward, return to space, and take his promotion, events are sent into the irrevocable spiral that will lead up to the climax.

Master and Commander: The Far Side of the World directed by Peter Weir (2004): When a convalescent Stephen, set loose upon his long-anticipated and long-delayed Galapagos expedition, accidentally discovers the Acheron at anchor on the far side of the island, the third act launches in a flurry of preparations. Jack formulates his plan to lure the enemy privateer in close enough for the kill, and his crew hurries to get everything ready for the battle we’ve all known was coming since the very first scene.

Takeaway value

As always, our best lessons are those we learn from the execution of great stories. So what can we glean from our chosen stories? How do they go about setting up and implementing the lengthy to-do list of the third act?

1. The third act begins around the 75% mark, although this timing is more flexible than it was with the previous acts. Sometimes the third act can begin as early as the 70% mark, although it rarely begins later than the 75% mark.

2. A major plot point marks the end of the second act and the beginning of the third. This may be an utter upheaval of the gains the character thought he made in the second half of the second act (as in Pride & Prejudice), an unexpected event (as in It’s a Wonderful Life), a personal decision (as in Ender’s Game), or a direct meeting between protagonist and antagonist (as in Master and Commander).

3. From its opening plot point onward, the third act picks up speed and isn’t likely to slow down.

4. However, the third act must be thoughtful enough in its first moments to allow all the pieces to either be completely tied off and set out of the way (such as Ender’s relationship with his sister) or assembled for the showdown (as in Master and Commander).

The third act is where stories are made or ruined. Everything that’s come before is important, but this is where the author’s mettle is tested. If we can deliver a solid third act, we’ve accomplished what thousands of novelists before us (even published ones) have failed to do. This is where writers become authors!

Stay tuned: Next week, we’ll talk about the Climax.

Tell me your opinion: Does your third act tie off all the loose ends?

  1. I try to tie off all the loose ends in my third act.. though it’s hard because I sometimes forget a few threads I left dangling in the first act. 😀

    Thanks for some good ideas.. 😀

    (would write a longer one, but I’m pressed for time atm)

  2. Thanks for commenting! I would go so far as to say it’s humanly impossible to tie off *all* the loose ends – especially in a large work of fiction. But a couple of read-throughs after the first draft can help us catch things we may have initially forgotten.

  3. I tie up the important threads; the main protagonist and plot lines for sure. I’m writing a series so some of the sub-plots are not properly wrapped and handed to the reader with a lovely bow. Because it’s a farily complex plot and I’m editing down, I’m not sure what to do with those loose-ish ends. I’d rather not cut them entirely, but I could rewrite them somewhat to indicate the result … don’t know if that would be any more satisfying than leaving them in mid-resolution. I have to give it some thought.

  4. In a writing a series, we have more leeway in tying up those loose ends, since we *want* to make the reader curious enough about them to keep reading. Just make sure you pay off in the sequel!

  5. Thanks KM! This was a great post 🙂

    I´m struggling with the problem I have really two plots on my WIP -what happens to the mother and what happens to the daughter after the latter runs away- and actually two stories, one after the other, that depends on each other and can´t be separated. That is making it impossible for me to really settle the structure (the character arc was complecated too, but I think that is now sort of sorted).

    Thank you,


  6. If you’re telling two concurrent stories, each will follow its own structure. You’ll want to align them, so their prominent plot points occur close to each other – and presumably bring them together by the climax.

  7. I´m trying so… but the story gets interrupted before it ends. When mother and daughter decide to go back… the former goes to prision and the second gets kidnaped, and they won´t meet each other again till after the whirlwind this unleashes for them :S

  8. It’s also possible that the stories can be integrated into one structure, so long as they influence one another significantly. For example, the first major plot point at the quarter mark could take place in the mother’s section, while the midpoint takes place in the daughter’s. But, in this instance, since the plots don’t each have their own complete set of driving plot points, they must be interconnected enough so that the plot point in one section can influence the progression of the other.

  9. Actually they are because what the daughter does will influence the mother´s quest. I´ll try and have that in mind. Thank you!

  10. If that’s so, then you’ve likely got a single-plot structure on your hands. Those are the easiest and most cohesive to pull off!

  11. I´m trying to figure it out just jotting down everything I have in my head so I can find an order to it later ^^

  12. Yes, it can be tough to see the overall structure until you know how the story as a whole is going to progress. That’s why I love outlines!

  13. You are SO right there! It´s hard stuff! lol

  14. Keep at it! You’ll get it all perfect sooner or later.

  15. It´s great to know I´m not the only one with this kind of trouble 🙂

  16. Nice post. Good job on writing about the Third Act.

  17. This is excellent and very inspiring.

    Thank you.

  18. @Meryl: Despite our solitude, one things writers always have is plenty of company!

    @Donna: Thanks for reading!

    @Mario: I’m glad you enjoyed the post.

  19. I’ve been loving this series of blogs and saving the different points in a spreadsheet so I can make myself a diagram of my stories and figure out what areas to emphasize and shift when I’m rewriting.

    Thanks so much for breaking this down. It’s been invaluable!

  20. A spreadsheet is a great idea! I’m going to put together a graphic for the final post. As a visual person, I always find it helpful to be able to see the overall plan at a glance.

  21. I really enjoyed reading this series. I am struggling right now with the plot of my contemporary romance, and balancing the heroine and hero’s arcs against the villain. The hero and heroine are at odds for most of the book, but there’s also the villain to consider. Sigh. Thank you for all of the time and effort you put into this. I can’t wait to read the rest.

  22. Sometimes POV characters will share plot points, sometimes the plot point of one will directly influence the other (negating the need for the other to have a corresponding plot point), and sometimes both will have independent plot points for the majority of the story. Usually, the first version is the most common, the easiest to pull off, and often the most cohesive.

  23. THANK YOU, just figured out some important parts of my third act!!

  24. Yay! Love it when that happens!

  25. Lisa Searle says

    I have thoroughly enjoyed this series and it has only resulted in making my story stronger and better. I have a great, well structured outline that I can’t wait to get started writing (albeit a little nervous about doing so!)
    It’s also made me conscious of the structure of books I’ve been reading and realising that those I haven’t enjoyed are because of their lack of structure and those I have are because of a solid one. Having a Kindle helps with seeing structure as well.

  26. Yes, Kindle is great for tracking story structure! Like the time counter on a movie, the percentage counter on the Kindle let’s you see exactly where you are within the story.

    Hey KM, this article is a great guide, just like the previous sections. I’ve got a question though, it is alright to shatter a character in the Third Part, just after the second plot point? Like intense humiliation which also serves as a major catalyst for the coming climax? The character has temporarily overcome his inner demons but is forced into a situation where the main antagonistic force broke him down in some other way. Looking forward for your reply!

    PS: This happens at near the end of the next chapter after the Second Plot Point

    • K.M. Weiland | @KMWeiland says

      First, let’s make sure we’re on the same page with our terminology. I call the Midpoint (at the 50%) the Second Plot Point. The Third Plot Point, which kicks off the Third Act, occurs at the 75% mark and is the low moment–the representation of death, from which the character must rise again to triumph. As such, everything you described is perfectly placed at the 75% mark plot point.

      • Lexsicon says

        Thanks KM!
        I’d like to apologize for the confusion back in my question. I used Larry Brooks’ Story Engineering terminology. The Second Plot Point I was talking about was actually the Third Plot Point.
        I also like to clarify my question again because I think my terminologies messed up what I wanted to say. After the Third Plot Point, when the characters temporarily overcome their respective Lies and Inner Demons and accepted the Truth, with their story and plot goals already within reach, is it alright if I make one of the characters so deeply humiliated that it will ultimately affect the climax? Thank you so much for this series. It’s helped me a lot!

        • K.M. Weiland | @KMWeiland says

          No problem! I know the differing terminology can get confusing. I just wanted to make sure we were talking about the same thing. You can have your minor characters experience their own low moments (if they have them) at slightly different times than the protag, so that’s fine. If you’re talking about the protagonist essentially experiencing another low moment of his own, that’s also fine–as long as it fits within his thematic progression from Lie to Truth. Even though he has “risen” from the Lie after the Third Plot Point, he will still face more progressively final moments of commitment to the Truth throughout the rest of the Third Act and sometimes leading right up to the Climactic Moment.

  29. My third act is all over the place and a failure after the middle of the book everything goes out of wack and is a complete flop. There’s some stuff that will work but it’s so out of order (?) and with many chapters not belonging that I need to scrap a lot of it. Well it’s my first book so it’s a learning process right? 😛

    Merryn is taken by Maxwell, Kar,. Her friends are either injured or unable to help. One was sucked into a cursed box. The god (he’s called unnamed as he can’t remember his name.) has taken control of her body/mind at this point, she fights back, uses it’s powers to toss Parcival and Han into a portal getting them away. Weird azz chapters after that>they get back togeatehr Merryn separates from the god (seriously I need to take that out it’s a confusing chapter.) Everyone fights to try and stop Unnamed,, but only Merryn can really do anything or she could if she wasn’t a spirit. (??) Ah ya it’s a mess. More chapters she gets her body back and everything goes crazy after that a big huge confusing mess.Cringe.

  30. Also, I wish I could give you a hug for making these articles. ^;^

  31. Elizabeth Mayor says

    In a three-act structure chart in a book that I reference frequently, an event happens at about the 75% mark called the Crisis, which is described as the “all is lost” moment. My problem is that the darkest moment in my book happens just a few scenes before the climax. Should I change the timing of this moment, or is the Crisis actually the Third Plot Point? In which case, what is the thing I thought was the crisis?

  32. Thank you so much for all the free articles and videos. I have so many notes now relating to the flat arc character, I’m feeling a bit overwhelmed. I have a question if you don’t mind – might you be able to suggest any novels where the protagonist’s Truth is not embraced by supporting characters? (there is no neat and happy ending for the book I’m writing). Thank you.
