The hunt is on to find the murderer of a wealthy glamorous heiress who is found dead in her London townhouse. Based on the short story by Agatha Christie.
When Leonard Vole is accused of murdering society lady Emily French, his solicitor Mayhew clings to the hope that Leonard's wife Romaine will provide the alibi that can save his life.
Romaine, whose testimony was Leonard's one hope to save him from the gallows, has turned on him, leaving Mayhew's case hopeless and Leonard's fatal verdict imminent.
