Mild-mannered doctor Jacob Henderson may appear to be successful and happy, but underneath the picket fence facade is a man frustrated and tormented by his cruel, adulterous wife and an insensitive world. After his wife flaunts yet another affair in his face, Jacob hires an assassin on the dark web to do her in while vacationing overseas. But he gets more than he bargains for as he soon develops his own taste for blood, and his addiction to violence attracts the attention of a gang of corrupt cops. As Jacob's hired assassin continues tying up loose ends with the doctor and the police, they all fall into a complex web of crime, murder and vigilantism that devolves into a murderous game of cat and mouse.
