Alaskan State Trooper Jeremiah Boone is not convinced the death of a university student is a random act when he finds a Native Alaskan weapon at the crime scene. Pushed by a political appointee and a fellow officer-turned-politician to disregard his instincts regarding a potential suspect, Boone resigns, leaving the murder unsolved, and the suspect still on the loose.

In an unlikely turn of events, the former State Trooper, now a US Marshal, unknowingly comes face to face with the suspect from his unsolved murder in the remotest place on earth, Antarctica. When women assigned at McMurdo Station report being stalked and assaulted, Marshal Boone’s instincts return to the former suspect. It’s up to him and his deputies to find the person or persons responsible for the assaults.

A desperate radio call from a science party in the Antarctic Dry Valley leads Boone on the path toward an encounter with the suspect responsible for assaults in McMurdo. Boone’s suspect forces a female science party member further into the remote valley, with intentions to continue his physical assault against the woman. It’s up to the marshal to find and confront his suspect before his actions claim another innocent life.
