Part 2/11:
Free diver Frederic Buyle leads the expedition, equipped with extraordinary diving skills, sensitivity to the ocean, and unparalleled courage. Frederic's goal is to explore the lost underwater paradise that the Mediterranean once epitomized, amidst tales of its decay into a polluted cesspool. Aboard the vessel Garlaban, he and a specialized team prepare for a three-week adventure that promises to reveal the secrets of the sea, specifically areas fifty kilometers off the coast of Marseilles near the wreck of the Donator, a freighter that sank in the aftermath of World War II.
