It's day 53 of the ice road season and only the toughest truckers remain on a road that's sent many people packing. Alex is part of a last great push to get some critical loads up the ice before it's too late. In his convoy is the heaviest load ever to cross the ice---a 100-ton electrical unit for the Diavik mine. If this load damages the ice, it could be the last run of the season. Rick, who may be suffering from frostbite, has hit his limit with driving a truck in forty below with no heat and needs to make a tough decision. The most unlikely survivor is rookie T.J. He's suffered some of the worst blows of the season, and although it's not yet over, he's already feeling like a seasoned veteran as he heads out on his 18th load across melting ice and a road that will soon disappear.
