Based on the bestselling book by Patrick Senecal, 5150 Elms Way is located at the end of a quiet street in a small town. When Yannick crashes his bike, he stumbles upon the Beaulieu residence seeking help, unaware of the horrors within - Jacques Beaulieu is a righteous psychopath and fanatical chess player, determined to rid the world of evil. His wife Maude has long put up with his physical abuse, but stays with her murderous husband to ensure the security of their youngest daughter Anne, a tormented child suffering since birth from severe mental illness. Oldest daughter Michelle is following in her fathers footsteps, hoping to take over the family business one day. Even though Yannick has done nothing wrong, he is beaten, tortured and tormented before Jacques makes him an offer: win at chess and he is free to go. So Yannick becomes a pawn in a deadly game - a game in which he will either lose his mind or his life.
