Raffles

Gentleman jewel thief Raffles (Ronald Colman) decides to give up his criminal ways as the notorious "Amateur Cracksman" after falling in love with Lady Gwen (Kay Francis). However, when his friend Bunny Manders (Bramwell Fletcher) tries to commit suicide because of a gambling debt he cannot repay, Raffles decides to take on one more job for Bunny's sake. He joins Bunny and Gwen as guests of Lord and Lady Melrose, with an eye toward acquiring the Melrose necklace, once the property of Empress Joséphine.

Complications arise when a gang of thieves also decides to try for the necklace at the same time. Inspector Mackenzie of Scotland Yard (David Torrence) gets wind of their plot and shows up at the Melrose estate with his men. Burglar Crawshaw breaks into the house and succeeds in stealing the jewelry, only to have Raffles take it away from him. Crawshaw is caught by the police, but learns his robber's identity.
