On the Dalton, Darrell Ward raises the stakes in his rivalry with Jack Jessee, but the north slope keeps him grounded as frost heaves threaten to shake his load apart. While Jack deals with Darrell's aggressive move, it's Atigun Pass that nearly takes out the veteran. Rookie Porkchop also struggles to climb Atigun Pass, and keep his streak of successful solo runs going. Austin is sent out on a heavy haul special assignment, but being forced to load the oversized cargo himself could be too much for the young heavy hauler.
