I feel the logline tells the reader who main characters are, what the problem is, they are in a Haunted Bed and Breakfast with Zero knowledge of how they arrived and it gives a since of irony because it raises the question which asks if maybe the characters are dead.
One issue I have which is they the story has Protagonist & Antagonist misdirects and I am not 100% sure how to convey either a true Protagonist or Antagonist without giving away to much.
Yet, the three are in and of themselves the Protagonist and the Haunted Bed and Breakfast is an Antagonist along with the disgruntled employee.
The story borrows from Hitchcock in the sense that Marion Crain died in Psycho and from the Wizard of Oz in the since that some of the same actors will play multiple roles like how Dorothy’s neighbor was the Wicked Witch.
Remember that a LOGLINE is referred to as a One-Line (and is usually 1 or at most 2 lines). You’re giving a synopsis.
A logline might be something like this:
A paranormal investigator, a writer, and a radio personality find themselves at an abandon B&B with no memory of how they got there.
You don’t need to give away Moses was a cop or Alex is unemployed, but I would use DJ or Talk show host (or whatever Laura does on radio). Also the shooting is in the story not the logline.
We know who they are, and what the story is from that one sentence. Why they’re there is why I’ll pay $15 to see.
