The men of the Jamie Davis Heavy Rescue company battle the treacherous Coquihalla Highway in British Columbia. Because it is one of the most economically important, most traveled trucking routes in North America, the crew must do whatever it takes to keep the road open. Truckers face steep hills, lethal drop-offs and major rockslides. The value of the cargo and the need for urgent delivery require the rescue crew to respond when truckers get into trouble. Owner Jamie handles the bills, the employees, keeping the clients happy, and the mighty ``Rotator.''
