Ice Road Truckers: The Complete Season Four (Blu-ray Disc, 2011, 4-Disc Set)

The intrepid Ice Road Truckers return to Alaska to haul some of the biggest loads they've ever contended with over an increasingly dangerous terrain, including the frozen rivers beyond the Dalton Highway. Jack Jesse hopes to maintain his status as the alpha trucker, while Lisa Kelly , one of the few female truckers on the haul roads, struggles to gain respect. Meanwhile, the rivalry between veteran drivers Hugh Rowland and Alex Debogorski continue to compete for superiority.
