在一个偏僻的山顶，有位神秘的陌生人从暴风雨中出现，向惠普利一家寻求庇护，而惠普利一家有著三个被妈妈严格管教的年轻人，以及失踪未果的神经质爸爸。这神秘的「陌生人」到底与惠普利一家和这间诡异的古堡有什麽关联？更可怕的是，某个夜晚，惠普利发现自己浸在血液中，束缚在床上无法动弹……。In a remote hill top mansion, a mysterious stranger emerges from a thunderstorm in the night, seeking refuge with the Whipley family; four young adults ruled by their strict religious mother, and their troubled father, who has vanished the previous night - But perhaps the 'stranger' is more connected to this family and to the dark unknown history of the house than they could ever suspect, and as the visitor begins to cultivate sexual tensions and paranoia within the house, the devilishly erotic history of the Whipley family threatens to lure them deep into its lustful, violent madness once again.
