The Last Adventure

Manu (Alain Delon) is a pilot who loses his license after a practical joke, and his closest friend Roland (Lino Ventura) is right there beside him in the wreckage of it. The jokesters, seeming sorry, point them toward a crashed plane lying on the ocean floor off the coast of Congo, said to be stuffed with riches. Robert Enrico sends the two friends after that treasure, with Laetitia (Joanna Shimkus) alongside, and nothing waiting at home to hold them.
