The Deep House

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