As experts predict one of the shortest and warmest winters on record, the ice road truckers face the biggest challenge in their history.

Lisa Kelly finds herself stranded hundreds of miles from the nearest town; Darrell Ward takes an off-road shortcut; Art Burke encounters a melting ice crossing and a full load; Steph Custance finds out whether she'll become part of the Polar team

As a short season looms, the drivers are up against it. Hundreds of miles from the nearest town, Lisa Kelly finds herself stranded. Darrell Ward rolls the dice by taking an off-road short cut, untested by any other truck. Art Burke squares off with a melting ice crossing and a load that's right at the weight limit. And twenty-two year-old Steph Custance finds out whether she'll be joining the Polar team.

Looking to expand their company, Darrell Ward and Lisa Kelly head into Alberta and onto a trail nicknamed "The Death Road." Art Burke faces off with the ice crossing where he nearly lost his life last season. And Polar's top dog Todd Dewey takes rookie Steph Custance under his wing as she embarks on her very first ice roads journey.

Twenty-two year-old Steph Custance tries to complete the first ice roads mission of her career, but a crossing that's just opened pushes her to the edge. As temperatures soar, Alex Debogorski runs into a road block. Art Burke serves as a diplomat for Polar, attempting to deliver to a new remote community. And Darrell Ward braves an unregulated winter road.

Darrell Ward faces a trail nicknamed "the obstacle course." Todd Dewey struggles to clear a melting ice bridge. Polar veteran Alex Debogorski is pushed to the limit hauling an oversized fuel tank. And Art Burke stumbles onto an ice crossing in the dead of night.

On her first ever solo trip, Polar rookie Steph Custance braves one of the longest ice crossings on the winter roads map. Darrell Ward attempts a triple delivery in a single day. An engine fire stops Lisa Kelly dead in her tracks. And Polar's top dog Todd Dewey celebrates his birthday stuck on the edge of a closed road.

Todd Dewey must fix his truck or be stranded a hundred miles from the nearest town. Alex Debogorski confronts a creek that's thawed in the middle of the road. On an important run for Polar, Art Burke receives news that could be devastating. And Lisa Kelly battles an ice crossing unlike any she's seen all season.

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