At the top of the world, there is a job only a few would dare. The mission: to haul critical supplies across 350 miles of frozen lakes to Canada's remote billion dollar diamond mines. Along the way the truckers contend with the most treacherous conditions imaginable: brutal temperatures, severe blizzards, frostbite and sleep deprivation, while constantly hoping that the 28 inches of ice won't give way and plunge them to their deaths. It's a 'dash for the cash', with each trucker racking up as many runs as possible in the eight short weeks before the ice highway melts. This mind-blowing series takes you through an entire perilous season, from the first enthusiastic runs to the risky final days when the ice becomes dangerously thin. Shot with 26 high-definition cameras in deepest winter, this is the story of the men who earn their living on thin ice.
