Her first day on the job is spent at an old villa deep in the woods on the outskirts of the countryside, caring for Deborah Jessel (Marie-Claude Pietragalla), an ex-ballet teacher who has fallen into a deep coma and is dependent on medical equipment to keep her alive. Legend has it that the villa is hiding valuable treasures, and Lucy, at the urging of her boyfriend William (Félix Moati), and their friend Ben (Jérémy Kapone) sneak into the villa one Halloween night to hunt for them. After some searching, however, it turns out that there seems to be someone else present in the villa besides Mrs. Jessel, and that is none other than Madame's supposedly long-dead daughter.

Unbelievable horrors occur one after another, and Lucy and the gang are in for a night they'll never forget. ......
