Troopers brave the dangerously frigid winter night as they hunt for a man who is threatening to end his mother's life, but the search gets complicated when the leads turn cold. Elsewhere in Alaska, Troopers are called to a remote native village to rid the community of an unwelcome intruder, and later, respond to a family camping trip turned violent. Troopers are then asked to sort out a stolen-car case with multiple twists and turns.

From a hot pursuit on ice-covered roads to a moose disrupting busy streets, no patrol measures up to the bone-chilling magnitude as those of Alaska's state troopers. In Fairbanks, Trooper Rallo is in dangerous pursuit of a stolen vehicle. Down in Palmer, a call comes out to Trooper Taylor of a car accident involving a moose on the Glenn Highway, where thousands of drivers commute every day. In Homer, Trooper Chaffin searches for the suspect of a local burglary before he flees the state.
