In the season five kick-off, we'll watch Troopers pursue suspects as spring beckons and the world's foremost sled race, the Iditarod, heats up. Patrolling the wilderness of the last frontier keeps the Troopers on their toes as people gather in March in Nome for one of the toughest races on Earth. Suspicious behavior at a gas station leads Troopers into a showdown with a suspect who locks himself in a bathroom in what looks like a last-ditch attempt to destroy his drugs.
