When narcotics detective Eugene "Mack" McCanick (David Morse) discovers that Simon Weeks (Cory Monteith) has been released from prison, he instigates a brutal manhunt, without permission from the Chief of Police (Ciaran Hinds). The frenzy of paranoia and violence that follows pushes Mack and his partner to the edge of the law. The closer Mack gets to his prey, the closer he gets to a secret from his past - one that only Weeks can expose.
