A night out clubbing in Paris takes a nasty turn for three friends (One Vietnamese, one African, one French), when they accept the invitation of the beautiful Eve to celebrate Christmas by visiting her house in the country. Once there they meet the manically grinning caretaker Joseph, who welcomes the out-of-town guests while his heavily pregnant wife Marie lurks upstairs. That evening, what begins innocently as Christmas dinner turns into disturbing conversations about sex, satanic possession and evil. As the weekend progresses Joseph's behavior only gets more erratic and the young friends realize their host has made a demonic pact. All hell is about to break loose.
