Okay. So the movie could have been better and what I figure happened was first of all the tea contained some sort of hallucinogen thereby explaining the painting that led to the lake with woman and chains and the other weird monster sounds and the one woman watching herself try to escape the room, etc. The ending when father and daughter are back in diner and then to car with yet another lock was them really still being in the game at the house tricking them to believe they escaped. They will NEVER escape and will spend the rest of their lives trying to survive the house.

This movie make no sense at all what happened at the end for Andrew and who behind all this and where is The Inventor . for the first half it was good, then loses it way in unclear nonsense
