Professor Taian Russo returns from a mysterious island with artifacts possessed by Heather, a 17th century Scottish ghost who after being accused of witchcraft was exiled to the island. Taian must find her peace before her possessive powers take full control.

Okay, so great draft and an interesting concept, but here are a few notes.

1, a logline should only be a single sentence. Your goal is to tell us who the main character is, what the conflict is, and what is at stake. It does not have to be in that exact order to my knowledge but this is the common formatting.

You already have the three pieces of information you need to get the right logline, so the struggle will be breaking this down to a single sentence. My advice is to not worry too much about the details about Heather and just focus on what matters the most. Main Character = Professor Taian Russo | Conflict = Finding peace for Heather | Stakes = Possession by a ghost.

2, I mentioned it above but as a future reference note, don’t be too concerned with how specific your details are here. The goal of the logline is to just present the bare concept of the story with no extremely detailed explanation. That comes with a synopsis.

Give it another shot and good luck!
