A woman brings her family back to her childhood home, which used to be an orphanage for handicapped children. Before long, her son starts to communicate with an invisible new friend.

The tragic murder of a 19-year-old girl reunites three childhood friends still living in Boston--the victim's gangster father, a detective, and the disturbed man they both suspect of killing her.

Set in France, Georges is a TV Literary Reviewer and lives in a small yet modern town house with his wife Anne, a publisher and his young son Pierrot. They begin to receive video tapes through the post of their house and family, along side obscure child-like drawings. They visit the police with hope of aid to find the stalker, but as there is no direct threat, they refuse to help. As the tapes become more personal, Georges takes it upon himself to figure out who is putting through his family through such horror. A true Michael Haneke Classic.
