De Havilland plays two roles in this entertaining psychological drama. A sister and her disturbed twin are implicated in a Hollywood murder and a police detective must figure out which one’s the killer.

Mortimer Brewster is a newspaperman and author known for his diatribes against marriage. We watch him being married at city hall in the opening scene. Now all that is required is a quick trip home to tell Mortimer’s two maiden aunts. While trying to break the news, he finds out his aunts’ hobby; killing lonely old men and burying them in the cellar. It gets worse.
