Dark Woods 2

An abandoned sanatorium is deteriorating in a remote forest in the mountains. The building is going to be demolished, and five contractors have taken on the task of inspecting the enormous building for hazardous materials. While attempting to shut off the water, they are led into a dark basement labyrinth. They soon find themselves face to face with the sanatorium's gruesome past. You can demolish a building, but never remove the past. (Warner Bros. Entertainment)
