During the two weeks it takes to complete the race, participants battle frostbite and overpowering fatigue. It's an arduous sport, but not a deadly one - until now. Someone is systematically killing the top competitors. And as the "mushers" thread their way along the trail, Sergeant Alex Jensen races to find the murderer. This is also the first year Jessie Arnold has a shot at winning. But as her position in the race improves, so do her chances of being the killer's next target.
