Truckers with nerves of steel take their lives in their hands driving heavily loaded vehicles across frozen lakes to deliver supplies to remote locations in Canada and Alaska. Whether they're bringing supplies to Canadian diamond mines, supplying offshore oil rigs in Alaska or even charting new territory driving over frozen swamps and rivers to bring much-needed supplies to small towns, these extreme truckers face troubles from their machines and from Mother Nature.

Art Burke attempts to keep his rig above ground on a melting ice crossing; polar driver Alex Debogorski battles his way up a mud covered mountain.

Darrell and Lisa fight to make it home over the hardest-hit trail; Art and the King of Obsolete reunite to haul a huge double trailer over a slick path; veteran Alex Debogorski races against the clock to deliver to a town in need.

The two rival companies work together to take on the biggest challenge in Ice Road Truckers history, pulling a cat train across the frozen Hudson Bay, but the untested ice shatters under the weight of the heavy haul.

Dave is at odds again with his bosses; Maya faces freezing brake line issues; Hugh hauls 30 tons of boulders across Lake Winnipeg; Rick takes the sidelines with truck repairs; Tony and Lisa honor a fallen trucker.
