In 1943, a German commando conceals a large quantity of gold in an undersea cave on the coast of Corsica. Years later, Schlumpf, the sole survivor of the commando, returns to Corsica to recuperate the treasure -- with British and Soviet spies on his heels, and closely monitored by Dromard, from the French intelligence services.
