While hauling loads north, the Ice Road Truckers hammer away at the weather, accident, and truck obstacles in their way. As Hugh and Rick deliver the largest load ever trucked on Manitoba's ice roads, their convoy comes to a sudden halt after downing a high-voltage power line. Lisa's dream of becoming a heavy haul push trucker depends on her ability to sync up with a new partner. Meanwhile, hoping for an easy run to pump up his load count, Alex pins up to ten tons of trouble. And haul road rookie Dave takes matters into his own hands to make a renegade roadside repair.

Rick and Hugh continue their marathon run, but the Winter Roads wreak havoc on the trucks leaving Hugh stuck on the side of the road. Alex comes to the rescue when a local family finds themselves stranded in the wilderness. Maya gets behind the wheel to take another shot at driving the entire haul road with Dave right behind her. And Lisa and Tony continue their heavy-haul convoy. But with her heavy-haul career on the line, the massive load proves to be more than Lisa can handle.
