The battle for supremacy on the winter roads begins a bold, new chapter. After two seasons of domination, Polar Industries is back to defend its place as load count champ in Manitoba, but Darrell Ward is ready to take on his former employer with his upstart company. Ward is also stealing one of Polar's superstar driver - Lisa Kelly - to help him try to win the fight; she returns more determined than ever after breaking through the ice at the end of last season. This is going to be an epic battle of David vs. Goliath as the tiny company is willing to brave any and all jobs in order to compete. The fortunes of both companies are put to the test as the thaw comes in record time. With big money and critical supplies on the line, there's no time to stop. The ice road truckers are forced to plough through the toughest conditions they've ever faced. It's a season for the ages and one the drivers will never forget.
