With a winter window shorter than ever and no time to waste, these drivers risk everything to haul in a lifeline of goods while chasing big paydays before the opportunity melts away under their chained tires. At the world’s northern edge, people and cultures cut off from civilization are briefly connected by a lifeline of roads paved with ice. Each year, a group of skilled, highly trained, and thrill-seeking truckers put their lives on the line to beat nature’s clock – battling dangerous roads, deadly frostbite, and brutal conditions to deliver life-saving supplies such as food and building materials to remote communities. This season, veterans like Todd Dewey and Lisa Kelly return with no hesitation – and no practice runs – while rookies emerge, determined to prove they have what it takes to reign supreme on the ice. With higher stakes, greater risks, and bigger rewards than ever before, it’s them vs. nature.
