Logline: Your Story's Core in One Sentence

Why it exists

A logline exists to communicate the commercial and narrative essence of a story in seconds. In industries like filmmaking or publishing, where decision-makers are flooded with ideas, a strong logline cuts through the noise and forces the writer to prove they have a clear, compelling concept before a single page is read.

The mental model

Think of a logline as the story's DNA. It's not the whole organism, but it contains the complete genetic code for what the story is about: the protagonist, their goal, the opposing force, and the stakes. It's the premise, not a chronological summary of the plot.

How it works

A logline combines the central conflict, the plot's synopsis, and an emotional hook into a single, concise sentence. It typically establishes a protagonist, the inciting incident that disrupts their world, their primary goal, and the main obstacle they face. It answers the questions: who is the story about, what do they want, and what's stopping them?

When to use it

Use a logline to pitch a screenplay or novel to producers and agents, in query letters, or in grant applications. It's the description you read on streaming services or in a TV guide. Many writers use it as a tool for themselves, to clarify their story's core before they start writing.

When not to use it

A logline is not a substitute for a full synopsis or treatment when one is requested; it's the hook, not the entire explanation. It's also less effective for highly experimental or non-narrative works where a central, character-driven conflict isn't the main point.

One canonical example

The one-sentence program summary in a TV Guide is a classic logline. For the film Jaws, a logline might be: "When a man-eating great white shark begins attacking a summer resort town, a police chief must overcome his own fear of the water to hunt the beast down." It states the protagonist, conflict, and stakes without detailing every plot point.
