Complications ensue when the male members of his gang get romantically involved with the natives, with Pete hooking up with 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.
