 Thriller about a psycho looking for revenge. Bronsky (Jean-Pierre Bisson) is a paraplegic because of an accident at a construction site that was partly due to the head architect, David Briand (Jean-Pierre Bacri). Many years after the accident, Bronsky shows up at Briand s residence with his family and his trailer looking for assistance. He and his wife insinuate themselves into the household without revealing their true identity. They start to work for Briand and his wife Elaine (Nicole Garcia) as a gardener and a babysitter with the sole objective of wreaking havoc on their lives and avenging Bronsky s disabilities.
