The Gun Runners

Sam Martin (Audie Murphy) runs a charter boat in the Florida Keys struggling to make a living and pay off his debts. After a major customer loses his gear and is arrested for passing bad checks, Sam tries to recoup his losses by pawning some of his gear and gambling with the proceeds. He agrees to take a wealthy gambler named Hanagan (Eddie Albert) on an overnight trip, unaware that Hanagan spends his time in Cuba arranging to deliver guns to rebel forces.
