A logline is a one or two sentence summary of a screenplay that captures the central conflict and hook. It answers: who is the protagonist, what do they want, and what stands in their way?

How do you write a good logline?

A good logline follows the format: When [inciting incident], a [protagonist] must [goal], or else [stakes]. It should be specific, hint at the genre, and make someone want to read the script.

How long should a logline be?

A logline should be 25-50 words — one to two sentences maximum. If you cannot say it in two sentences, your concept may not be focused enough.

What Makes a Great Logline?

Formula: When [inciting incident], a [specific protagonist] must [clear goal], or else [high stakes].

Example: "When a great white shark begins terrorizing a small beach town, the police chief must team up with a marine biologist and a grizzled shark hunter to kill it before the 4th of July weekend." — Jaws

Tips: Be specific (not "a man" but "a burned-out detective"), show the stakes clearly, hint at the genre, and keep it under 50 words.
