John Seale directed this lively, though overly familiar, adventure tale. Frank Flynn (Mark Harmon) is a jazz musician who travels to the South Seas to look for his missing brother Charlie. Once there, he takes up with an attractive hitchhiker named Anna (Deborah Unger). When he finds out that his brother has been bludgeoned to death by a group of natives, Frank decides to investigate the case on his own. Frank meets Charlie's former business associate, Robert "Viv" Vivaldi (Jeroen Krabbe) and his insouciant manner causes Frank to suspect he may have had something to do with his brother's death. Anna then reveals herself to be Viv's ex-wife and Frank's badgering of Viv causes both Frank and Anna to flee into the jungle, where they come upon some curious gold bars. Frank then recalls their father had mentioned something to Charlie about an American bomber that had crashed in the jungle, loaded with gold. Viv then catches up with the duo and, although Anna is captured, Frank befriends a group of natives who teach him the ways of the South Pacific Islanders. They also lead him to the location where the plane full of gold went down; they then help Frank lay siege to Viv's home.
