Steve Daggett (Cameron Mitchell) fights to protect Fidel Castro from dangerous pro-Batista counterrevolutionaries. Steve comes to Cuba to find his friend Hank Miller (Logan Field) who has been missing for a while. It turns out that he has been captured by Fernando (Eduardo Noriega), the leader of the pro-Batista forces, who needs Hank to convert their airplanes into bombers. Steve's former girlfriend Monica (Allison Hayes) is now Mrs. Hank Miller.
'Pier 5, Havana' was filmed in the Los Angeles area just after the Cuban Revolution. The Errol Flynn semi-documentary Cuban Rebel Girls and the black comedy Our Man in Havana were shot on location on the island in the same post-revolution period.
