How to Write a Screenplay Logline: A Practical Guide

Start with the story, before the wording

Before polishing a sentence, write four plain answers: Who are we following? What changes their situation? What do they try to achieve? What makes that difficult? If those answers describe four different stories, the problem may be the focus of the draft rather than your choice of words.

Give the protagonist a useful identifying detail. A job, responsibility or contradiction can tell us more than a name. An anxious emergency dispatcher suggests a different story from a retired burglar, even if both receive the same threatening phone call. Choose the detail that affects the action rather than a string of flattering adjectives.

Give the protagonist something to do

A situation becomes easier to grasp when the central action is specific. A woman confronting her past could describe many films. A woman trying to recover a stolen recording before her estranged daughter hears it gives us an objective and a source of pressure.

The objective can be emotional or modest. A teenager trying to persuade his father to attend a school performance has something concrete to pursue. You do not need to invent a murder, a deadline or a global threat to make a quiet drama sound more commercial. The promise should match the film you have written.

Connect the obstacle to the stakes

Name the main force opposing the goal. It might be another person, an institution, a physical situation or the protagonist’s own damaging behaviour. Avoid listing every complication. One central obstacle usually communicates the shape of the struggle more clearly.

Then ask what failure costs this particular person. Losing a job means something different to someone supporting a sibling than to someone preparing to resign. Stakes become persuasive through context. Phrases such as everything is at risk often hide the detail a reader needs.

A worked example

Here is an invented starting point: A bus driver has a difficult night and learns to stand up for herself. It gives us a character and a theme, but little sense of the story we will watch.

A more specific version: When a missing teenager boards her final night bus, a driver facing dismissal must get him to safety while his pursuers track the route. We can now identify the protagonist, the triggering event, the objective and the opposition. Her employment situation adds a potential cost to abandoning procedure.

This is an illustration, not a required formula. The revised sentence would misrepresent a reflective family drama about the same driver. Test your wording against the actual screenplay, including its tone and the protagonist’s degree of agency.

Trim without removing the distinctive detail

Try a version of roughly one or two sentences. Remove supporting character names, backstory and broad claims such as unforgettable or groundbreaking. Keep the detail that makes the central conflict particular. Brevity helps only if the reader still understands the story.

Ask someone unfamiliar with the draft what they think the film is about. If they describe a different goal or genre, revise the promise. A useful logline creates accurate curiosity. It cannot compensate for a screenplay whose central action remains unclear.
