A young woman is acquitted of the murder of her husband, who died in suspicious circumstances. The film then goes into flashback to portray the events leading up to his death. Sally Raynor's aviator husband Martin has been missing for two years and is believed dead, during which time she has fallen in love with a local doctor, John Harper, whom she plans to marry. When Martin unexpectedly returns from Brazil still alive, she decides to give up the doctor and go back to her life with Martin, although their marriage had not been a happy one. Over the next six months his erratic behaviour, brought on by his ordeal, makes Sally believe he is insane. A close friend of the family, Arthur 'Glan' Glanville, also realises this, as does Dr John Harper and the family's housekeeper. Martin's mother also sees his strange behaviour, but chooses to ignore it. On one of his wild nighttime walks, he attacks someone, a man who only survives by chance. Glan finds evidence of this and tells Sally, saying they must immediately get Martin treatment in a mental hospital, to prevent him being sent to jail. Sally asks Martin to agree to treatment, but the thought of losing his freedom, as happened in Brazil, terrifies him, and he begs her to help him by finding another way. Sally plans to kill him with an overdose of sleeping tablets to protect him from society's punishment, but can't go through with it. Instead, he commits suicide, but Sally is charged with his murder. Glan believes she is innocent, but Martin's mother, despite having seen her son attacking Sally, believes she is guilty. Although innocent of his death, Sally is haunted by guilt and, even after a jury clears her of murder, she is hesitant to marry the doctor she loves.
