Adventurer Pat Morrison learns that $3,000,000 in gold was hidden from the Japanese invaders of Corregidor during the early days of World War II, and he decides to go after the loot. Since the gold was buried in the labyrinths of Malinta Hill by an Army detail of four men who thought they were hiding official records, Morrison recruits the same four men for his expedition. Former officer Trev Jones is now an alcoholic who has led his daughter Bobby to believe that he is dead; Jesus Jimenez Riley is a Moro pearl diver whose wife, Mariko, steals pearls from her husband and is having an affair with Morrison; Draco is a burly Apache living in Arizona; and the bigoted Hansen is now a merchant seaman. Draco arrives from the States and joins Morrison, Riley, and Jones in breaking Hansen out of the jail where he is being held on a morals charge. As Morrison is about to put his plan into action, however, Jones is kidnaped and held by an unscrupulous blackmailer known as Wombat. Wombat informs Bobby that her father is alive and will be returned to her for a fee of $500 plus sexual favors. Morrison comes to Bobby's aid, and the two develop a mutual attraction. Once Morrison and his men have rescued Jones, they set out to recover the gold. Reenacting the parts they played in burying the gold many years ago, the four men eventually lead Morrison to the cache. Success turns to disaster, however, when Hansen and Draco come to blows and their fighting disrupts Morrison's time schedule. Hansen is killed by the Philippine guards, and the others are captured. After learning that the jealous Mariko tipped off the authorities, a handcuffed Morrison waves farewell to Bobby as she leaves to return to the United States.
