Roulette (1924)

Lois Carrington becomes the ward of gambler John Tralee when her father drops dead during a card game with Tralee. Tralee educates Lois and gives her a home of her own, but he uses her as a decoy in his gambling joint, where she meets Peter Marineaux. When Peter suspects that Lois helped Tralee to cheat him, she offers herself in payment. Tralee objects, but the two men play with both Lois and the money as stakes. Lois controls the roulette wheel to make Peter the winner, and they are married.
