The battle lines are drawn in Manitoba, Canada. Hugh “Polar Bear” Rowland returns after quitting his job at Polar Industries and sets up his own shop right down the street. Bound and determined to reclaim his crown as “King of the Road,” he poaches Polar’s dispatcher, intent on landing enough loads to force his old company into submission. Hugh rounds up the toughest truckers he can find and they hit the winter roads. However, Polar Industries and its owner, Mark Kohaykewych, aren’t about to take this challenge lying down. To counter this threat on their turf, they enlist some of Hugh’s biggest rivals. Ice road legend Alex Debogorski signs on with Polar as well as Alaskan trucking icon Lisa Kelly, after a year hiatus. Montana legend Darrell Ward is also enlisted by the crew at Polar. This season also chronicles an eccentric mechanic way up north who dances to the beat of a completely different drum. Joey Barnes, nicknamed “The King of Obsolete,” fills his yard with trucks from decades past. Many of the vehicles are rarities, and some have been re-engineered as Joey’s own unique pieces of equipment. He’s taken it upon himself to use his fleet of trucks to rescue those stuck in the most remote corners of Manitoba.
