Who Finds a Friend Finds a Treasure

Alan Lloyd (Terence Hill) has a map to treasure the Japanese army left on a Pacific island at the end of World War II, and a pack of gangsters who want it. He hides aboard the boat of Charlie O'Brien (Bud Spencer) and quietly tampers with the compass, so Charlie never learns where they are headed. Sergio Corbucci sends the pair into the sort of friendship that only forms when two people are stuck on a boat together.
