Hugh struggles to repair a vehicle that has been left in the Arctic cold for four years; a driver gets stranded on a weak part of the ice in freak weather conditions; and Drew takes his first ride on ocean ice.
The series begins with drivers Hugh, Alex, Rick and Drew travelling 100 miles north of the Arctic Circle to use a new ice road. In other shows, Rick damages the oil panel underneath his rig; Jack tows a pick-up truck out of a snowdrift; and Lisa experiences a whiteout as her mission to transport a cargo of heavy tyres continues.
Novice driver Ray faces a treacherous mountain pass, and in other editions, a devastating wreck brings new driver Greg's rivalry with Jack to an abrupt end; and the drivers are forced to think fast when they are hit by a phase-three storm in the Atigun Pass, Alaska.
A new run begins with Hugh setting up his own rival company, pitting untested drivers against his adversary's team of old hands. In later shows, Hugh's latest recruit gets stranded; Alex takes a giant forklift on a dangerous trip; and Hugh's trucking empire begins to unravel.
