Hillary Graham (Clifford Evans) accidentally kills Bob Fenwick (Lloyd Lamble) who had had an affair with Grahams' wife Carla (Nora Swinburne) 9-years ago. But Graham's business partner Richard Munroe (Stratford Johns) who visited Fenwick after Graham was there was arrested for the crime as his wife Eileen (Mary Laura Wood), also had an affair with Fenwick. The couple's son Harry (David Aylmer) breaks up with his fiancee Pauline (Dorothy Bromley) after Harry realizes Pauline doesn't care for anyone but her self. Graham won't let Munroe take the blame and eventually calls Scotland Yard to confess a half an hour after Munroe is cleared of the crime because two wintesses saw him knock at Fenwick's door but did not go in the apartment. The Inspector (Michael Nightingale) arrives to arrest Graham.
