Reserved academic Professor Richard Wanley (Edward G Robinson) becomes interested in the portrait of a young woman he sees in a window, and then he meets the model Alice (Joan Bennett)! They become friendly and he goes back to Alice's apartment to see other artwork, there when Alice's boyfriend (Arthur Loft) storms in and attacks Richard. Richard kills the man in self-defence.
But the nightmare has only just begun. Richard discovers that the man is a successful industrialist. He hides the body but when it looks like they might have got away with it, the man's bodyguard (Dan Duryea) turns up to blackmail them...
A well structured film full of tension and pretty dark. It soon becomes clear that Richard is pretty doomed and his quiet comfortable life has been changed forever. However, the surprise ending might be a step too far.
