His spartan existence on the casino trail is shattered when he is approached by Cirk, a vulnerable and angry young man seeking help to execute his plan for revenge on a retired military major. Tell sees a chance at redemption through his relationship with Cirk. Gaining backing from mysterious gambling financier La Linda, Tell takes Cirk with him on the road, going from casino to casino until the unlikely trio set their sights on winning the World Series of Poker in Las Vegas.
