Richard Arlen is the convicted murderer and Adrienne Ames his sister who believes in his innocence. We see the murder and the framing set-up at the beginning of the film, so there’s no mystery for the audience to solve. Just the pleasure of watching an intricate cat-and-mouse game, with the murderer one step ahead of his pursuers until the final, tense confrontation.
