Dennis O'Keefe is the manager and co-owner of a Las Vegas casino. It's another ordnary day. A woman has gambled away most of her and her husband's savings, and she wants him to return the losses. A small-town banker and his wife are vacationing, and he decides that he can afford to lose $3,000, but wins instead. Gangster Thomas Gomez, newly released from Alcatraz, wants revenge and the casino. And schoolteacher Coleen Grey is researching a book on how you can't win against the house, so she and O'Keefe fall in love.
O'Keefe offers a world-weary performance that is telling, but the principal interest is old-time actors in small roles: Robert Armstrong as one of Gomez' henchmen, Charles Winninger and Elizabeth Patterson as the banker and his wife, Mary Beth Hughes as a losing gambler.... it's the downside of the ending of the studio system: all these talented actors in small roles that brighten this definite B movie for a few seconds.
