Miami businessman Steve Daggett (Cameron Mitchell) arrives in Havana in the wake of the revolution, looking for his army buddy Hank (Logan Field), a hard-drinking mechanic who has suddenly vanished. Steve follows a trail that leads him to the apartment of his old flame -- Hank's current wife, Monica (Allison Hayes) -- and to a boat shop where he is beaten up by strangers and warned to leave Cuba. He discovers that Hank's disappearance is linked to a conspiracy to depose Fidel Castro.
