The latest installment of the adrenaline-pumping survival series sees reigning haulage king Jack Jessee attempt to defend his hard-won title, Lisa Kelly fight to prove herself in the male-dominated world of trucking and ice road veteran Alex Debogorski duke it out against his long-time rival, Hugh 'The Polar Bear' Rowland. Meanwhile, cocky comeback kid Greg Boadwine and rookie Ray Veilleux seek to make their mark driving some of the toughest routes on earth. Flaring tempers, failing brakes and monster storms all conspire to create one of Ice Road Truckers' most dramatic seasons ever, as the heroic hauliers take on the brutal Alaskan winter and each other in a bid to be crowned king of the ice roads!
