Melvyn Douglas, (Arsene Lupin) keeps his real name a secret from everyone and gets himself involved with a stolen necklace and also has a romantic relationship with Lorraine DeGrissac, (Virginia Bruce) who both give an outstanding performance throughout the entire film. There is plenty of laughs and comedy in this film and it captures your attention and then turns quickly away from stolen jewelry and centers around all the characters involved in this mystery. George Zucco, (Perfect of Police) instead of playing the role as a crook which he has done all his acting career, is now a police man who tries to catch his criminal and suspects Arsene Lupin of stealing this necklace. Georges Bouchet, (Monty Wolley) plays low key in this film and has some very dark secrets which he does not want to reveal.
