When the monster's insatiable hunger upsets his scheme, Capetto decides to sink his boat into 30 feet of water off the shore of a small island and then to retrieve the gold later. Complications ensue when the male members of his gang get romantically involved with the natives, with Pete hooking up with the aptly named Porcina (Esther Sandoval) and Jack with her pretty daughter Mango (Sonia Noemí González), and local working girl Carmelita (Blanquita Romero) takes an instant liking to Sparks.
