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.
