How to Write a Screenplay Synopsis (With a One-Page Example)

How to write a screenplay synopsis: the short version

A synopsis tells the whole story of your screenplay on one page. Present tense, third person, four to six paragraphs, 350 to 500 words. It names the protagonist and what they want in the first paragraph, walks through the turns of the story in order, and ends with the ending. It is not a teaser and it is not a review. Its job is to let a reader decide, in two minutes, whether the script has a complete and well-shaped story inside it.

The steps:

1. Start from your logline. The synopsis is that sentence expanded, so if the logline is wrong the synopsis inherits the error.
2. List the eight to ten events that change the story's direction. Not every scene: the turns.
3. Write one paragraph per act, or one per major movement, in present tense, in the order the audience experiences them.
4. State the ending plainly in the final paragraph, including what the protagonist does and what it costs.
5. Cut to one page. Remove subplots that do not touch the spine, minor characters, and every adjective that describes your own writing.

If you are unsure how this differs from the longer document producers ask for, read what a treatment is. The short answer: a synopsis summarises, a treatment tells.

What to include in a synopsis, and what to leave out

The ending is not optional. A reader who reaches the last line and finds the resolution withheld assumes the writer does not have one. Contest readers, coverage readers and assistants writing a one-paragraph report for their boss all need to know how it ends, and none of them will request the script to find out.

Names are the other adjustment from the logline. A logline describes the protagonist by type because the reader has no context. A synopsis has a page of context, so use names: NOOR, 41, at first mention, then Noor.

How to structure a one-page synopsis

The synopsis follows the shape of the film, which for most features is three acts. If you are working from the three-act structure or a beat sheet, the paragraphs map onto it directly.

• Paragraph 1: the world and the want. Who the protagonist is, what their life looks like, and what they want or lack. Two to four sentences.
• Paragraph 2: the inciting incident and the decision. What breaks the routine and what the protagonist chooses to do about it. This is the end of the first act.
• Paragraphs 3 and 4: escalation and the midpoint. The plan, the complications, the antagonist pushing back, and the reversal that changes what the protagonist is fighting for. Keep cause and effect visible: "because" and "so" are your most useful words here.
• Paragraph 5: the low point and the climax. The moment it looks lost, the choice that follows, and the confrontation it produces.
• Paragraph 6: the resolution. What happens, what it costs, and what is different now. One to three sentences. No moral.

Each paragraph should end on a change. If a paragraph ends with the situation the same as it started, either the paragraph is describing setup rather than story or the script has a flat stretch, and it is cheaper to find that out here.

THE LAST SHIFT — Thriller — 98 pages

A night-shift air-ambulance dispatcher who spots a helicopter flying a dead patient must find out what her own company is smuggling before the crew that runs it realises she is listening.

NOOR HADDAD, 41, has worked the overnight desk at a private air-ambulance company for nine years, since her husband's death left her preferring the hours when nobody asks how she is. She is good at the job and invisible in it. Tonight a pilot she has never met, DESMOND REYES, 55, checks in from a helicopter that her screen says is still in the hangar.

Her supervisor tells her to log it as a tracking fault. Noor pulls the manifest instead and finds the listed patient died four days ago. She says nothing, records everything, and by dawn has a folder of flights that carried people who do not exist. When she brings it to the company's medical director, MARGARET OKAFOR, 60, Margaret thanks her, takes the folder, and reassigns her to days.

Days are worse. Noor is watched, her badge stops opening doors, and a pilot she trusts is grounded after talking to her. She learns the flights carry cash across the state line for a clinic chain Margaret part-owns, and that Desmond is the only pilot who has never asked what he is carrying. She approaches him. He refuses to help, then, after a flight where the cargo turns out to be a person, changes his mind.

Together they plan to expose one flight in the air, live, to the state regulator. Margaret discovers the plan and gives Noor a choice: a settlement and silence, or a fabricated record showing Noor herself altered the manifests. Noor takes the settlement. Desmond thinks she has sold him out.

On the night of the last smuggling flight before the audit, Noor returns to the overnight desk. She has taken the settlement so she would have the access badge back. She routes Desmond's helicopter into restricted airspace on an open channel, forcing a military intercept, and reads the true manifest to the regulator over the radio while Margaret listens from the hangar. Desmond lands the helicopter with the cargo intact and the state police waiting.

Noor loses the job and the settlement. In the final scene she is on a day shift at a public hospital dispatch, answering a call, and someone asks how she is. She tells them.

Notice that every paragraph ends with something changed, the ending is on the page, the cost is named, and the last line carries the character arc without a word about theme. That final beat is what a reader means by "it lands".

Synopsis for contests and query letters vs a treatment

The same story gets summarised at three lengths for three readers.

Contests usually specify a word or page limit and sometimes a tense. Follow it exactly; a synopsis that breaks the limit is the first thing a screener notices. Some contests also ask for a shorter "brief synopsis" of 100 words alongside the full one. Write the full page first and cut down; it is far easier than building up.

In a query letter the synopsis shrinks to a paragraph and loses the ending, because the query's job is to get the script requested, not to prove it is complete. The free query letter and one-pager generator builds both versions from the same inputs so they stay consistent.

Writing the synopsis from a finished script

Writing the synopsis after the draft is the more common case and the more useful one, because it audits the script. The efficient method is to work from the scene list rather than re-reading the pages.

1. Write a one-line synopsis for every scene: who wants what, what changes.
2. Mark the scenes where the story turns. There should be eight to twelve in a feature.
3. Write the synopsis from the marked scenes only. Everything else is texture.
4. Read the result. If a turn is missing between two paragraphs, the script has a gap there too.

Zen Writer's scene navigator is built for step one: every scene has a synopsis field next to its heading, and the whole list reads as a summary of the script without opening a second document. Writers who fill it in while drafting have the synopsis half-written before the draft is done. It works the same on every platform, and Zen Writer's free online screenplay editor has the navigator too, with no login.

Once the synopsis is done, check it against the script for drift. The most common finding is that the ending you summarised is better than the one you wrote, which is a note worth having before anyone else reads either. The screenwriting guides cover the rewrite from there.

Synopsis mistakes that mark a draft as amateur

1. Withholding the ending. "Will Noor expose the truth before it is too late?" is a trailer, not a synopsis. Say what she does.
2. Scene-by-scene retelling. If the synopsis runs three pages, it is an outline. Keep only the turns.
3. Opening with a character list. Introduce people when they enter the story, with an age and a role, and not before.
4. Reviewing your own script. "In a heart-pounding climax" and "a poignant final image" are claims. Let the events make them.
5. Tense drift. Present throughout. "Noor pulled the manifest and finds" is read as carelessness.
6. Subplots at equal weight. The romance or the sister's illness gets one clause if it touches the spine, and nothing if it does not.
7. No cost. A resolution where the protagonist wins and loses nothing reads as a first draft. Name what it took.
