Brace for the impact of another hard-riding season of IRT. Our danger-addicted truckers can’t escape the pull of Alaska’s Ice Roads where huge new monster loads and new ice routes over swift waters severely push the limits of success…and survival. Hugh, Alex, Lisa and Jack return, competing with new rigs and new drivers –a potent mixture that tests their strengths and everything they know about trucking on the deadly ice roads. It takes cool heads to handle the coldest road on earth. Truckers hauling vital cargo to remote northern outposts race against time to deliver their loads before the road literally melts away into open ocean. It's a deadly but lucrative game, with hundreds of miles to travel at temperatures plunging to 60 degrees below zero -- in places with chilling names like Coldfoot and Deadhorse. This road, once used as a migratory route, continues to play a vital role in history as Ice Road Truckers (Alex, Hugh, Jack and Lisa) take the wheel for another season. Like their trailblazing forefathers, these truckers continue to carry on the lone wolf entrepreneurial spirit that built America, taking huge risks in the hopes of receiving huge rewards. Our truckers will once again embark on a race against the elements, against time and against each other. This groundbreaking series will continue to examine this time honored profession that dates back almost a century, often through generations of families.
