Two adventurers and best friends, Roland and Manu, are the victims of a practical joke that costs Manu his pilot's license. With seeming contrition, the jokesters tell Roland and Manu about a crashed plane lying on the ocean floor off the coast of Congo stuffed with riches. The adventurers set off to find the loot.
