There's something strange going on at Deadlock House, a secluded French retirement home.The residents seem like nice people, but employees are disappearing and the whole place seems a bit odd. The boarders are vegetarian, the house director plays the same creepy tune on the piano over and over again, and one man, in particular, seems overly violent and aggressive. Unfortunately for Martine (Isabelle Goguey), the new staff nurse, she's about to discover the horrifying secret of Deadlock House… a secret so horrifying, she may not live to see the dawn.
