An Act of Murder stars Fredric March as a husband faced with an impossible predicament in this controversial drama that was well ahead of its time. Calvin Cooke (March), a no-nonsense judge in a small Pennsylvania town, finds his thoughts turning to end the life of his beloved wife Cathy (Florence Eldridge) when he learns that she has an incurable disease and is suffering from unbearable pain. He decides to move forward with his plan and then surrenders himself to the police. Defended by a brilliant attorney (Edmond O'Brien), Cooke goes on trial for his life in a case that will decide if he's legally guilty of murder or morally innocent of killing his wife.
