Day 53 of the ice road season. A large amount of critical loads still need to get up the road and Alex is part of the last great push. His convoy carries the heaviest load ever to cross the ice, a 100 ton electrical unit for the Diavik mine. Rick may be suffering from frostbite and has hit his limit driving a truck in forty below with no heat. T.J. heads out on his 18th load across melting ice and a road that will soon disappear.
