 Mexico miner Pete Carroll (Peter Adams) is in Acapulco and meets Terry Perreau (Andrea King) and falls in love with her after he hears her singing (or dubbed) on a recording of "Extrano Amour (Strange Love.) The troubled Terry decides she wants to go shark fishing, so Pete poses as the skipper of a fishing boat, owned by Thursday (Ramon Sanchez), and off they go. Pete lands a mantray and cuts it up for bait and the sharks are soon swarming, and Terry dives in the water. Terry does likewise and fights a few sharks and gets his leg gaashed but finally rescues her. Gradually, her friendship also turns into love. But back in Acapulco she learns of Pete s "fake skipper" joke, is all hacked off and goes to Mexico City with her friend Dr. Antez (Enrique Zambrano.) There, a specialist, Dr. Rivas (Eduardo Alcaraz) tells her that unless she has a dangerous operation she has only three months to live. Depressed even more than usual, if possible, she returns to the hotel and is met by!
