Troopers respond to a series of harrowing calls in the dead of the Alaskan winter. Trooper Cresswell and Sgt. Acton are seriously out-gunned by an armed man barricaded inside a home in a small, Native Alaskan village. Back in the Mat-Su Valley, dispatch receives a frantic domestic abuse report, and upon arrival at the scene, troopers sort through conflicting stories. Meanwhile, Trooper Cronin heads toward a tough warrant arrest of his own at a suspected meth house.
