Never Trust a Gambler proves the veracity of its title by offering up a particularly unsavory specimen in the form of Steve Garry (Dane Clark). Vowing that he's sworn off gambling, Steve is taken back by his loving ex-spouse Virginia Merrill (Cathy O'Donnell). In fact, Steve is merely using Virginia as a shield, to avoid testifying as a witness in a San Francisco murder trial. It seems that he's the murderer, and as such is obliged to kill again to cover his tracks. Poor, deluded Virginia doesn't catch on to her former husband's perfidy until it's nearly too late. Never Trust a Gambler is well-stocked with reliable supporting players, including Tom Drake, Jeff Corey, Myrna Dell and especially Rhys Williams.
