Pushing the Edge

S5 E1: The Ice Road Truckers are back in action, and the roads are more dangerous than ever. Lisa's first run of the season goes south in a hurry. Two rookie drivers raise the stakes in the "Dash for the Cash." And old pros Hugh and Alex, along with wildcard Rick Yemm, leave Alaska behind to take on some of the most remote and deadliest roads on the planet. Then, Hugh and Rick roll deeper into the Canadian outback, while a dangerous overflow may leave Alex stranded in the wilderness. Dave's training run with Tony reaches the boiling point. Lisa Kelly goes on a rescue mission. And Maya's first look at the Haul Road may be enough to send this rookie back to the big city. (2 hours.)
