Overview:As the end of the season nears, Polar tries to fulfill their contract over the unregulated road to Utik Lake. But when a jackknifed truck blocks the remote trail, it's up to Darrell Ward to move the wrecked rig all by himself. Lisa Kelly also braves the path to Utik with her heaviest haul of the season, and the melting roads give her a ride she'll never forget. New Polar hire Art Burke struggles on his first solo run as engine problems threaten to shut him down. At VP, rookie Todd Dewey's excavator haul causes multiple tires to blow out from under the massive weight. And The King of Obsolete's crew breaks through the ice at one of the northernmost destinations on the winter roads.
