Les Audacieux plot
Diver Charles Madigan has the difficult task of informing the daughter of his best friend Villion about her father's death. She turns out to be a beautiful young woman, whom he falls in love with. At the same time, a bloody robbery takes place on a truck carrying diamonds. One of the robbers makes off with the loot and is found dead by Madigan a few days later in a wreck at the bottom of the sea. Big question: where are the diamonds? From that moment on, a great quest ensues that also does not leave Madigan untouched, because there appears to be a relationship with the death of Villion.
