Classic British crime drama starring Vivien Leigh, Leslie Banks and Laurence Olivier. Keith Durrant (Banks) is a brilliant young barrister on the verge of being promoted to the bench. His plans hit a snag when his younger brother, Larry (Olivier), accidentally kills the ex-husband of his girlfriend, Wanda (Leigh), and asks Durrant for help. Durrant realises that he cannot go to the police because he may run the risk of ruining his promotion, so he says nothing. When a tramp is arrested for the murder, Larry knows he must turn himself in before the man is sentenced for a crime he did not commit. Sentencing takes place in 21 days, so Larry and Wanda decide to enjoy those days in the best way they can. However, when the tramp dies in prison, Larry is torn between confessing or living with the guilty secret forever.
