The Shark Hunters (1963)

Aurelio is a shark fisherman who works on the coast of Tabasco, Mexico. He works hard and sends money to his wife and children, who live in Mexico City. Although he misses his family, he's rather happy on the coat; he even has a romance with a native girl. One day he decides to return to Mexico City, where his brother-in-law is waiting to invite him to join his business.
