The Deep House Review

Tina and Ben are a young engaged New York couple and passionate YouTube contributors seeking out reputedly haunted houses across Europe to live-record their experiences. They go to seek out a sanatorium submerged in an artificial lake in Southwest France but find it a busy vacation spot. Pierre, a local, offers to take them to a different section of the lake in Chanteloup forest, an area which was artificially submerged in 1984 to prevent frequently recurring, devastating floods. He claims to be leading them to a site with a perfectly preserved mansion.

Tina and Ben submerge after reaching the spot, finding the house in a short while, with its contents strangely well-preserved. However, bizarre things begin to happen after they enter the house; they hear strange noises and voices. Their drone's motion sensor detects movement when there's nothing to trigger it, and their electronics malfunction for seemingly no reason. They find satanic symbols and a score of violent scratches at the front door post, and some of the rooms contain lots of photos, posters, and news articles showing missing children. Finally, they open a door blocked by a large cross and find that the room contains two corpses suspended above a satanic pentagram in torture masks and chains, along with a side room containing pickled human body parts. Tina and Ben try to flee the house, but a brick wall suddenly blocks off the window they entered through, and their frantic search for other exits is in vain.

Tina is suddenly attacked while trying to open a gate in the cellar with the two bodies. The assault ceases abruptly, but Ben strangely denies anything strange happening. Ben is curious and reveals the corpses by removing their masks; they are the Montégnacs, the family who owned the house. The two corpses come to life and chase the couple through the house. The shaft collapses as they try to escape through a chimney, trapping them on different floors. Ben finds a family tree featuring Pierre in an upstairs bedroom, revealing him to be the son of the Montégnacs and indicating that he lured them to the house on purpose before an undead girl attacks him - the Montégnacs' daughter Sarah - and possessed by her. He leads Tina to a hidden sitting room in the basement once she finds him where Sarah, through Ben and a demented film reel, shows that Pierre and Mr. Montégnac used children from the surrounding area as satanic sacrifices. An avenging mob eventually killed the elder Montégnacs and Sarah, but Pierre escaped.

Ben, possessed by Sarah, tries to convince Tina to join the family. Panicked and with a depleted oxygen supply, Tina escapes into a secret satanic chapel, where she finds a shaft leading to the surface. Ben reaches her and tries to kill her, but she wounds him with a diving knife, shocking him out of his possession. Before they can escape together, Sarah stabs Ben to death. The Montégnacs then turn on Tina, but she escapes up the shaft, which leads back into the lake. But just below the water's surface, the remaining air in her lungs gives out, and she drowns.

There is a brief scene after the credits in which two new divers look out over the lake, accompanied by Pierre.
