In a New York hospital, a man is cured of heroin addiction after a grueling three-month treatment. Although no longer an addict, he has complete amnesia: the only clues to his past are an expensive ring he was wearing when admitted, and a book of matches from a Puerto Rican nightclub. He pawns the ring and buys clandestine passage on a boat to Puerto Rico in search of his identity.

Tin Tan sets off for adventure on the isle of Puerto Rico. This musical comedy takes place in the International Airport of Puerto Rico during a day of carnival. Knowing the problems that go hand-in-hand with the carnival, the airport director appoints a team to deal with a threat from an anonymous letter.
