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.

Before the first storm of the ice road season strikes, Davey Lennie is called to rescue a stranded trucker; a blizzard makes ice roads impassable and dangerous, shutting down operations; Rick has two accidents in four days.

MGM breaks camp to move everything to a new base, including its 135-foot, $250,000 derrick -- the tallest and most expensive structure in the Arctic; Drew Sherwood's first big rig solo is only to deliver junk food; a storm strikes.

After the storm clears, all the truckers are ready to roll except Rick, who is on the verge of quitting and seeks advice from Hugh; Jerry makes a second attempt at moving the MGM camp with a "two trucking" technique.

After delivering the fragile 135-foot derrick to the MGM exploration site, the truckers must also transport its base, an 80-ton substructure that ranks as the heaviest and most-dangerous load of the season.
