Directed by Eric Cherrière

Film Synopsis

Pierre Tardieu is a forty-something man who lives in Toulouse in an old house with his father, who is stricken with Alzheimer's disease.  He earns a modest income by doing any odd jobs that come his way.  It is a dull and monotonous life and no one seems to be aware of Pierre's existence.  But this muscly middle-aged man has a dark secret.  At night, he prowls the streets looking for young people he can abduct.  Taking them back to his house, he holds them prisoner in the cellar and then kills them.  As he goes on his killing sprees, Pierre takes great care not to give himself away.  So far, no one suspects him of murder, but that is about to change...
