While diving in a remote French lake, a couple of YouTubers who specialise in underwater exploration videos discover a house submerged in the deep waters. What was initially a unique finding soon turns into a nightmare when they discover that the house was the scene of atrocious crimes. Trapped, with their oxygen reserves falling dangerously, they realise the worst is yet to come: they are not alone in the house.

As well as providing the subject for Luc Besson’s The Big Blue, Jacques Mayol did more than anyone to establish the sport of free diving to enormous depths without an oxygen supply. Using breathing techniques derived from yoga, he went to 50, 60, and even 100 meters—depths no one had considered to be within the bounds of human possibility. Mayol was a sportsman, a mystic, a vagabond, but above all, a man who believed in testing the limits of experience. This visually stunning tribute shows a man’s quest to be at one with the vastness of the ocean and to have no fear of the abyss within, where lurks serenity, freedom and finally, death.
