Save the Cat is one of the most popular ways to outline a story, and one of the easiest to misuse. Used as a rigid formula it produces predictable books. Used as a checklist, it is a quick way to see whether your story has the turning points readers expect. This guide explains each of the fifteen beats in plain language, shows what they look like in a real story outline, covers where they fall in a novel, and explains when to bend them. The last section shows how to build the whole thing as a board in Quillen.
The short answer
Save the Cat divides a story into fifteen beats across four acts: Opening Image, Theme Stated, Set-Up, Catalyst, Debate, Break Into Two, B Story, Fun and Games, Midpoint, Bad Guys Close In, All Is Lost, Dark Night of the Soul, Break Into Three, Finale and Final Image. You write one or two sentences for each beat about your own story, and the outline shows you where the story sags or rushes. In Quillen, applying the Save the Cat template gives you all fifteen beats as ready-titled cards on a board, in four act columns.
Where it comes from
The method comes from Blake Snyder's screenwriting book Save the Cat!, which breaks a film into beats. Novelists adopted it because most commercial stories, in any medium, follow a similar arc: a flawed hero, a disruption, a commitment, a midpoint twist, a collapse and a rebuilding. Snyder's beats are described by their position in a film; for a novel, you treat them as proportions of the whole book.
The fifteen beats, one question each
The easiest way to use each beat is to turn it into a question about your story and answer it in a sentence.
Act 1: the world before and the disruption
- Opening Image. What does the reader see first? It should show who the hero is and what is wrong, in a single image.
- Theme Stated. What is the story about underneath the plot? Someone mentions it early, usually without the hero understanding.
- Set-Up. What is the hero's ordinary world, and what flaw or lack will the story fix?
- Catalyst. What happens that makes ordinary life impossible?
- Debate. Why does the hero hesitate? This is where you earn the reader's belief that the next step is a real choice.
Act 2A: the new world
- Break Into Two. What choice does the hero make, and what do they leave behind?
- B Story. Which relationship or secondary plot will carry the theme?
- Fun and Games. What is the "promise of the premise"? Give the reader the scenes the cover and blurb suggested.
Act 2B: the pressure
- Midpoint. What false victory or false defeat changes what the hero thinks the story is about?
- Bad Guys Close In. How do outside enemies and inner doubts press harder?
- All Is Lost. What is the lowest point? Something must end, often with a sense of loss.
- Dark Night of the Soul. How does the hero take in what has happened?
Act 3: the resolution
- Break Into Three. What new idea, often tying the A and B stories, shows the way?
- Finale. How does the hero apply what they have learned to beat the problem?
- Final Image. What closing image mirrors the opening and shows how things have changed?
Where the beats fall in a novel
Beat sheets are usually given as percentages of the whole story. Treat them as approximate guides, since plenty of good books break them. For an 80,000-word novel, they work out roughly like this:
| Beat | Roughly where | In an 80,000-word book |
|---|---|---|
| Catalyst | About 10 to 12% in | Around 8,000 to 10,000 words |
| Break Into Two | End of Act 1, about 20 to 25% | Around 16,000 to 20,000 words |
| Midpoint | About halfway | Around 40,000 words |
| All Is Lost | About 75% | Around 60,000 words |
| Break Into Three | About 80 to 85% | Around 64,000 to 68,000 words |
| Final Image | The very end | Last page |
The practical use of those numbers is diagnosis. If your Catalyst arrives at 30,000 words, your first act is probably doing too much set-up. If your Midpoint is at 25,000, your middle will feel rushed.
A worked example: The Salt Road
Here are all fifteen beats for the fantasy novel we use as a running example in these guides. Notice how short each answer is: a beat sheet is a sketch, not a synopsis.
| Beat | What it does | In The Salt Road |
|---|---|---|
| Opening Image | A snapshot of the hero's world before the story starts. | Mara paces out a road alone on the salt flats at dawn, a map case at her hip. |
| Theme Stated | Someone, often not the hero, hints at what the story is really about. | An old surveyor tells her, "A road belongs to whoever dares to map it." |
| Set-Up | The hero's ordinary life, flaws and what is missing. | In Orrin, Mara is paid by merchants, owes the surveyors' guild, avoids her sister, and fears the deep flats. |
| Catalyst | The event that ends life as usual. | The Tollmaster seals the salt road. Mara's maps are declared a crime. |
| Debate | The hero hesitates. Should they act? | Run, hide or finish the map? Mara argues with her sister and the guild. |
| Break Into Two | The hero commits and enters a new situation. | She takes the sealed survey and leaves Orrin through the forbidden gate. |
| B Story | A secondary thread, often a relationship that carries the theme. | Her sister Ilsa, a clerk in the Tollmaster's office, becomes a secret ally, and the story asks who can be trusted. |
| Fun and Games | The promise of the premise: what the reader came for. | Charting the unknown flats, dodging patrols, reading mirages: Mara finds the lost road. |
| Midpoint | A false victory or false defeat that raises the stakes. | She finds the lost road, and learns it leads to the Tollmaster's own hidden salt vault. |
| Bad Guys Close In | Pressure grows from outside and inside. | Guards track her. Ilsa is exposed. The guild disowns Mara. |
| All Is Lost | The lowest point. | Her map is burned and Ilsa is arrested. |
| Dark Night of the Soul | The hero absorbs the loss before the final push. | Alone on the flats, Mara realizes she has only ever mapped for other people. |
| Break Into Three | A new idea shows a way forward. | The map is in her head, and Ilsa's ledger can prove the vault exists. |
| Finale | The hero proves what they have learned and resolves the conflict. | Mara leads the caravans down the road in daylight while Ilsa's ledger exposes the Tollmaster. |
| Final Image | A snapshot that mirrors and contrasts with the opening. | Mara paces out another road at dawn, with a crowd walking behind her. |
How to fill it in
- Start with the ending. Write the Final Image and the Finale first. Knowing where the story lands makes the earlier beats easier.
- Fill the five big turns next: Catalyst, Break Into Two, Midpoint, All Is Lost, Break Into Three. These are the skeleton.
- Fill the rest in order, one sentence each.
- Check the theme. Look at Theme Stated, Midpoint and Dark Night together. Do they push the same question forward?
- Check the B Story. It should show up in Act 2A, return in Bad Guys Close In and matter in the Finale.
- Then turn each beat into one or more scenes, and add the goal, conflict and outcome for each scene.
When to bend or skip a beat
Save the Cat is a diagnostic tool, not a law. A literary novel may have no real midpoint reversal. A mystery may spread its Catalyst across several chapters. A quiet story may not have an obvious Dark Night of the Soul. If a beat does not fit, reshape it or skip it, and ask what your story does instead. The danger is not breaking the beats; it is writing a book in which every beat arrives on schedule and none of them surprises the reader.
Common mistakes
| Mistake | Problem | Fix |
|---|---|---|
| Treating the percentages as rules | The story feels mechanical | Use them to diagnose, not to dictate |
| Writing a summary instead of a beat | The outline becomes a long synopsis | One or two sentences per beat |
| A weak Catalyst | Nothing changes, so the Debate feels artificial | Make it an event that ends the hero's old life |
| Ignoring the B Story | The theme never lands | Plan how it appears in each act |
| A Midpoint that changes nothing | The middle sags | Make it a real shift in stakes or understanding |
| Finishing the outline and never revisiting it | The outline and the draft drift apart | Update the board as the story changes |
Do it in Quillen
Quillen's outline board has a Save the Cat template that sets up all fifteen beats for you.
- Open your book and click Outline at the bottom of the left sidebar. You start on the Board view, which holds columns of cards.
- Click Templates at the top right. A list of four outline templates appears with a plain-language explanation of each. Applying one only adds columns and cards; it never touches anything already on your board.
- Find Save the Cat and click Apply. Your board fills with four columns (Act 1, Act 2A, Act 2B, Act 3) and the fifteen beats as cards, each with a one-line reminder of what the beat does. Act 1 gets Opening Image, Theme Stated, Set-Up, Catalyst and Debate. Act 2A gets Break Into Two, B Story and Fun and Games. Act 2B gets Midpoint, Bad Guys Close In, All Is Lost and Dark Night of the Soul. Act 3 gets Break Into Three, Finale and Final Image.
- Open a card by clicking it. Replace the reminder in the Summary box with your own story's beat.
- Add Goal, Conflict and Outcome in the box below, which is useful for the big turning-point cards. Use Notes to list the characters, lore and chapters involved, and Arc tags to label a card with a subplot or character arc.
- Rearrange freely. Drag cards between columns or within a column, and drag whole columns to reorder them. Click Add Card in any column for an extra beat, or Add Column for a new section.
- Switch to Timeline if you want to see the same cards as a single running sequence. Its order is separate from the Board, so you can reorder one without moving the other.
When the board is filled in, your outline lives next to your manuscript in the same app. You can keep it open as you write, and adjust it as the story changes.
