A logline is a one or two sentence description that captures the core idea of a movie as clearly as possible. It is not a full summary. Think of it as the movie’s cleanest “hook,” built from a few essentials: who the main character is, what they want, what stands in their way, and what is at stake if they fail. A strong logline also hints at the tone or genre, so you immediately know whether you are in thriller territory, romantic comedy territory, or something else. If you can read it and picture the movie, it is doing its job.
For example, here is a basic logline structure: “When [inciting incident] forces [protagonist] to [goal], they must [main obstacle] before [stakes].” A classic example is Jaws: “When a killer shark terrorizes a beach town, a police chief teams with a marine biologist and a grizzled fisherman to hunt it down before more people are killed.” Notice how it stays focused on the central conflict and urgency, without trying to cover every subplot or character. That is the difference between a logline and a synopsis. The logline sells the premise with precision, while the synopsis explains the story in broader detail.
