Ning and Kwin are a couple with a 7-year-old daughter, Ing. The three of them decide to move to a condo room and rent out their house to two tenants: Ratree, a retired doctor, and her 40-year-old daughter, Nuch. After the new tenants have moved in, Ning notices that Kwin begins to exhibit unusual behaviour. He becomes secretive and often disappears from the condo at 4 a.m. Kwin even sports a triangle-shaped tattoo – the same design as Nuch’s.
As her husband’s behaviour becomes more and more disturbing, Ning also realizes that her daughter is being preyed on by some unseen sinister force. She has to do everything to protect her daughter from this dark cult!
