Alex Debogorski races to complete one of Polar's most critical hauls of the season after a dashboard fire nearly costs him more than just a paycheck. Lisa's forced to stop in the middle of a frozen lake when she loses sight of the road. Darrell Ward's patience with Polar reaches its limit after he fails to receive a promised load. At VP Express, Art Burke and Todd Dewey run into trouble when they find their high priced hauls frozen in the snow. And the King of Obsolete's convoy breaks through the ice on one of the most remote trails in Manitoba.
At the top of the world, in the coldest parts of North America, there is a whole trucking industry that most people had never heard of. Some communities and industries can only be reached for a few months each year, when rivers or seas freeze over. Ice Road Truckers features the activities of drivers who operate trucks on seasonal routes crossing frozen lakes and rivers in remote arctic territories in Canada and Alaska.
Seasons 1 and 2 are based in Canada's Northwest Territories, first the diamond mines around Yellowknife and then the Mackenzie River ice road from Inuvik. Seasons 3 and 4 move to the USA and focus on Alaska's improved but still remote Dalton Highway, supplying the oilfields in Prudhoe Bay. Seasons 5 and 6 split coverage between Alaska and the winter roads Winnipeg, in Canada's Manitoba, while Alex heads farther north than ever before on the deadly Dempster.
