Polar driver Steph Custance braves one of the longest ice crossings on the winter roads map and to make things worse, she is all alone. Darrell Ward attempts a triple delivery in a single day, meanwhile Lisa Kelly is stopped dead in her tracks by an engine fire. Todd Dewey celebrates his birthday stuck on the edge of a closed road.

As the end of the season nears, Polar Boss Mark Kohaykewych makes a historic deal with Darrell Ward and Lisa Kelly to team up for a four truck convoy over a closed road. Alex Debogorski must complete one of the longest trails in the final hours to make a delivery and Art Burke's truck breakdowns on the ice.

The four truck convoy faces fire and an ice crossing so thin, they must test the thickness themselves. After Art Burke's engine dies, he must ride back with Alex Debogorski to Winnipeg over a trail that destroys the old pro's truck.
