A pregnant college student named Sapphire Robbins (Yvonne Buckingham) is murdered in London's Hampstead Heath. When police superintendent Robert Hazard (Nigel Patrick) discovers that the victim was a light-skinned black woman passing as white, it upends his initial assumptions. Hazard and his openly racist assistant (Michael Craig) explore the city's racially tense underground jazz scene as they interview suspects, including Sapphire's white fiancé (Paul Massie).
