A logline is a one sentence written pitch, always in present tense form, that clearly defines what the film or tv show is all about. Using the main story as a guide, our loglines succinctly and accurately convey what the core of the story is about.
A successful logline should follow the protagonist's journey, his or her major goal and conflict/obstacle. We often define your protagonist by divulging their profession. And we always use strong adjectives to describe any of the characters.
