In pre-Second World War England, a leading film star and his wife attempt to recover a secret carburetor stolen by enemy agents. Based on a popular stage musical starring Hulbert and Courtneidge, a husband-and-wife team who had made a series of successful comedy films during the 1930s.
In pre Second World War England, film star (Jack Hulbert) is recruited to be a spy. Together with his wife (Cicely Courtneidge) he attempts to recover a secret carburretor stolen by enemy agents.
At first his wife suspects that Jack is having an affair with his glamorous co-star as he is behaving suspiciously. Jack eventually reveals he been asked to go undercover.
This is a rather heavy handed musical-dance caper. It moves briskly enough with some silliness but is not that funny. Hulbert is amiable enough but Courtneidge overpowers the film by being over the top.
