Rising temperatures are melting away the ice road, making it a dash to the finish line for the crew breaking down the Langley site. Every last piece of equipment must be transported down the ice to Inuvik before the Arctic waters reclaim the road. Hugh is hauling an unsteady load of heavy gauge cable, making his rig so back-heavy that he struggles to get traction on the slippery surface. One wrong move could spell disaster for Hugh, but also for rookie Devon Neff, who makes his debut run at a time when the road is at its most fragile. And as the action escalates on the road, Rick finds himself in familiar territory--Gruben's garage. He has loads to pick up, but yet again this season, they'll have to wait until his truck is repaired.
