While diving in a remote French lake, a couple of YouTubers who specialize 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 realize the worst is yet to come: they are not alone in the house.
