5150 ELM'S WAY is located at the end of a quiet street in a small town. When Yannick Bérubé falls off his bike, he knocks at the door of the Beaulieu residence so he can clean the blood off his hands. But Jacques Beaulieu and his family have other plans for Yannick. Beaulieu is a righteous psychopath and fanatical chess player who wants to rid the world of evil. And even though Yannick has done nothing wrong, he is beaten, tortured and tormented before Beaulieu makes him an offer: win at chess and he is free to go. And so Yannick is now a pawn in Beaulieu's game—one in which he will either lose his mind or his life.
