Like most Sam Katzman efforts of the late 1950s, Miami Expose laid claim to being "torn from today's headlines." Lensed on location, the film stars Lee J. Cobb as dedicated police lieutenant Bart Scott. Though he'd like nothing better than to smash Miami's gambling racketeers, Scott is forever stymied by legal loopholes. It becomes personal when an old friend of Scott's is killed during a turf war between ageing gambling czar Raymond Sheridan (Alan Napier) and hot-headed upstart Louie Ascot (Michael Granger). Patricia Medina plays Lila Hodges, sole witness to the murder, who is placed in protective custody by Scott all part of a master plan to bring the syndicate bosses out in the open. Also appearing as a "bought" politician is Edward Arnold, who died during production.
