The Girl in Number 29

Laurie Devon (Mayo) is a New York playwright who refuses to work on another play. One night he sees a woman in an apartment across the street take out a gun and place it to her forehead. He reaches her in time to save her, and she tells him that she is under some terrible evil influence. The woman is taken to a house on Long Island, where Devon after a fight rescues her. He takes out the revolver and shoots one of the pursuers, who falls to the ground.
