"Champagne" Charlie Courtland (Paul Cavanaugh) is a smooth, sophisticated and highly unethical gambler, plying his trade among the rich and famous. Charlie's backers hope for a huge financial windfall when he begins to court beautiful young heiress Linda Craig (Helen Wood). At the last moment, however, Charlie scotches the wedding plans, whereupon he is killed by one of his cohorts. The murderer is himself murdered, and suspicion falls upon Charlie's faithful valet Fipps (Herbert Mundin), who presumably "done it" to protect the heroine from a blackmail scheme. So the butler did it, eh? Don't be too sure!
