Most writers stall at the exact same place. They've got their one-sentence summary -- tight, punchy, the story in a nutshell. Then someone says "expand it," and suddenly that beautiful seed drowns in subplots, side characters, and worldbuilding tangents that have nothing to do with the original idea. Two pages later, the story is unrecognizable.

The problem isn't adding details. It's adding the wrong details.

A one-paragraph summary isn't a miniature synopsis. It's a cause-and-effect chain. The beginning detonates the middle. The middle forces the end. The end is the only possible result of everything that came before. Hollywood screenwriters call this three-act structure: Setup, Confrontation, Resolution. Sounds textbook-simple until you try doing it in five sentences -- exactly five -- and realize you have to forge every link in the chain with zero slack.

That's what step two of the Snowflake Method demands.

Why Five Sentences?

Three-act structure. So why not three sentences?

Because acts aren't the point. Turning points are.

Randy Ingermanson designed the logic like this --

Sentence 1: Background setup + inciting incident. What does your protagonist's world look like, and what blows it apart?

Sentence 2: First disaster. End of Act One. The protagonist gets pulled into the story's whirlpool. No exit.

Sentence 3: Second disaster. Dead center of the story. Something flips the protagonist's understanding or circumstances -- the rules change.

Sentence 4: Third disaster. End of Act Two. The darkest corner. Everything looks impossible.

Sentence 5: Resolution. How does the protagonist face the final test? Where does the story land?

Sentences 1-2 hold up Act One, 3-4 carry Act Two, 5 is Act Three. But the real value isn't in labeling acts. It's in locating the four turning points -- the joints of the skeleton. Remove any one of them, and the whole structure collapses.

Why the Word "Disaster"?

Ingermanson doesn't say "event." Doesn't say "turning point." He says "disaster." That word choice is deliberate.

Think about the most common plotting mistake beginners make: the protagonist hits a problem, solves it. Hits another, solves that too. Cruising through the story like a video game with cheat codes on. Readers check out by page three -- no cost, no pain, no tension.

"Disaster" is a slap across the face. It says: every turning point should make things worse, or at least messier.

Not necessarily apocalyptic. Maybe --

The plan worked, but the price makes your stomach turn. The goal was achieved, only to reveal the goal itself was a trap. An ally switches sides. The protagonist's deepest fear gets dragged into daylight. The thing they wanted most arrives -- and something more precious disappears.

One rule: every turning point backs the protagonist into a narrower alley. The audience keeps watching because the alley keeps shrinking and the protagonist still hasn't found the exit.

Classic Example: Rocky

Theory's done. Let's tear apart a real movie.

One-Sentence Summary:
A washed-up boxer unexpectedly gets the chance to fight the world champion and must prove he's not "just another bum."

One-Paragraph Summary:

1. Rocky Balboa is a third-rate Philadelphia boxer making a living as a debt collector for the mob. His life is a dead end -- the only light is Adrian, the shy girl at the pet shop he can't stop thinking about.

2. World heavyweight champion Apollo Creed, hungry for publicity, picks an unknown nobody to fight as "the guy who gets demolished." He chooses Rocky for an absurd reason: "The Italian Stallion" sounds good on a poster.

3. Rocky starts training but can't focus. He doesn't believe he has a shot. Then old trainer Mickey shows up at his door, offering to coach him -- and that trust forces Rocky to confront a brutal question: has he been waiting for opportunity all these years, or hiding from effort?

4. Night before the fight. Rocky sits on the bed, tells Adrian he can't win. Apollo is too good. But he's going to "go the distance." Nobody has ever lasted fifteen rounds with Apollo. If he can pull that off, he'll know -- he's not just another bum carried out on a stretcher.

5. Fifteen rounds of blood. Both fighters beaten beyond recognition. Decision: Apollo wins. But the entire crowd is on its feet. Rocky didn't win the fight -- he won back his dignity, and he won Adrian's love.

Three things worth noticing about this structure.

Disaster doesn't mean bad news. Getting the challenge sounds great, right? But for Rocky it's also massive exposure -- his weaknesses, his years of wasted potential, all laid bare under ring lights. Good disasters always cut both ways.

Disasters deepen in layers. From external pressure (physical training) to internal interrogation (who am I, really?) to the final decision (abandon the fantasy of winning, just don't go down). Each layer cuts deeper into the character's core.

The ending mirrors the beginning. Opening Rocky believes he's a hopeless failure. Closing Rocky proves he's not just another bum sent up to take a beating. Same question, two answers, arc complete.

Another Example: When Harry Met Sally

Different genre. Romantic comedy disasters look different.

One-Sentence Summary:
A man and a woman, after a disastrous first meeting, decide to be friends -- only to discover that men and women might not be able to stay "just friends."

One-Paragraph Summary:

1. Harry and Sally share a car ride to New York after college graduation, arguing the entire trip about whether men and women can be purely platonic friends. They part on terrible terms.

2. Five years later, an airport encounter -- Sally is about to move in with her boyfriend, Harry just got engaged. Five more years, a bookstore run-in -- this time both are freshly out of relationships, bruised and raw. They decide to try the friend thing.

3. The friendship deepens. They become each other's 3 a.m. phone call, the person who knows everything. Then one vulnerable night, they cross the line. Everything detonates.

4. Harry has no idea how to handle this "more than friends" situation. He retreats, dodges, pretends nothing happened. Sally is gutted. They drift apart. She starts seeing someone else. Harry finally realizes -- he may have lost the most important person in his life.

5. New Year's Eve. Harry runs through New York streets, finds Sally at a party, tells her he loves everything about her -- including every single thing that drives him crazy. They're together.

Notice the "disasters" here -- no explosions, no car chases, no external crises. In romantic comedy, disaster is the relationship itself becoming more complicated. Every time equilibrium seems possible, the relationship lurches into deeper chaos. That's where the tension lives.

Using AI to Explore Different Paragraph Versions

A one-paragraph summary, like the one-sentence version before it, rarely comes out right on the first try. It needs kneading. Like clay.

In Slima's Writing Studio, press Cmd+Shift+A (Mac) or Ctrl+Shift+A (Windows) to open the AI Chat Panel. Try this prompt:

I'm using the Snowflake Method to plan a novel. Here's my one-sentence summary:

"[paste your one-sentence summary]"

Expand it into a one-paragraph summary (five sentences) following this structure:
1. Background setup + inciting incident
2. First disaster (end of Act One, protagonist dragged into the story)
3. Second disaster (midpoint, attitude or circumstances shift)
4. Third disaster (end of Act Two, darkest moment)
5. Resolution

Requirements:
- Each "disaster" must make the situation more complicated or more painful
- The resolution must grow naturally from previous developments
- Generate 2 versions: one emphasizing external conflict, one emphasizing internal conflict

The AI fires back two versions. Maybe Version A has a killer opening, Version B sticks the landing -- splice them, graft a third version that's better than either. This isn't laziness. It's real creative process: let the AI generate possibilities, then you decide what stays and what gets cut.

Creating Your Paragraph File

Satisfied with a version? Open Slima's File Tree and give it a dedicated home:

    ├── 01-one-sentence.md
    └── 02-one-paragraph.md   # New file

Organize it like this:

The value of this format isn't neatness. It forces one critical question: how does each disaster actually make the story harder? If the "How It Makes Things Worse" column stays blank, your disaster might not be disastrous enough.

Using Split Window to Compare Sentence and Paragraph

The easiest mistake when writing the paragraph isn't writing too much or too little -- it's drifting off-course.

The one-sentence summary is story DNA. The paragraph should unfold that DNA, not mutate into a different species. But mid-draft, a shiny new idea hijacks your attention, and by the time you look up, the paragraph is telling a story the sentence never promised.

Fix is simple. Press Cmd+ (Mac) or Ctrl+ (Windows) to open Slima's Split Window. One-sentence summary on the left. Paragraph draft on the right. Glance over constantly: "Are all five sentences expanding the core concept? Or has one wandered off to talk about something else entirely?"

That's the design philosophy behind Slima's Writing Studio -- writing isn't just inspiration. It's engineering. And engineering needs good tools.

Open the AI Chat Panel again. Try this:

Evaluate this one-paragraph summary's structure:

[paste your five sentences]

Criteria:
1. Does each "disaster" genuinely complicate things? Or is it just "something happened"?
2. Is the resolution a natural result of previous developments? Or does it need a deus ex machina?
3. Is the protagonist's arc clear? What state do they start in, what state do they end in?
4. Any obvious logical holes?

Point out problems and give specific revision suggestions.

AI won't write your story. But it sees things you can't -- especially logical cracks. Because you know your story too well. Connections that feel obvious to you might only exist inside your head, never making it onto the page. Let AI flag those blind spots. Then you decide how to patch them.

Common Mistakes

Writing a one-paragraph summary has a few deep pits.

Too detailed. The paragraph is skeleton. Skeleton doesn't grow flesh. The moment you start describing the light in a scene, what a character is wearing, the back-and-forth of a conversation -- stop. That's muscle and skin. Later steps handle those. Right now, one sentence per element. One is enough.

Too vague. "Then some things happened and the protagonist made a decision." What things? What decision? A vague summary is a vague map -- looks like there's a road, but follow it and you're lost. Be specific. Not detailed -- specific. There's a difference.

Disasters that don't hurt enough. Check your turning points. If any of them sounds like "things worked out" or "the problem got solved," that's not disaster. That's fairy tale. Every turning point should make readers -- and the protagonist -- wince. Not because something bad happened, but because things got more tangled, choices got more painful.

The ending drops from the sky. Possibly the worst structural flaw. If the resolution requires an element never mentioned before -- a character who materializes, an ability never hinted at, an accident that conveniently occurs -- the structure has a hole. Look back at the three disasters. Did they plant seeds for the ending? If not, the problem isn't the ending. It's the disasters.

Save Versions, Adjust Anytime

A one-paragraph summary isn't carved in stone. Every step of the Snowflake Method circles back to influence the step before it.

After character design, you might realize the second disaster needs reworking because the protagonist's motivation shifted. During outlining, you might discover the resolution needs adjustment because the story has drifted from its original trajectory. Normal. Expected.

Use Slima's Version Control (Cmd+Shift+G or Ctrl+Shift+G) to create a Snapshot. Freeze each significant version. Save one before a major overhaul, another after. Even if you turn the paragraph inside out, you can always return to what came before.

Iteration isn't evidence of failure. Iteration is the substance of creation.

Next Steps

What's in hand now? A one-sentence summary, plus a five-sentence skeleton. Beginning clear, three disasters building pressure layer by layer, resolution growing naturally from everything that came before.

This skeleton can hold a story. But a skeleton doesn't walk on its own -- it needs characters.
