A routine swashbuckler set during the 18th century when pirates still roamed the Spanish main, this adventure film stars popular Mexican idol Pedro Armendariz as the appropriately named Captain Tiburon (Capt. Shark). Tiburon and his first mate Taursus (Rodolfo Hoyos) bury two treasure chests on a remote island, and then Taursus betrays the Captain by shooting him and leaving him for dead, with plans to come back later and pick up the loot.
