Featuring compelling extreme winter wrecks and roadside rescues on Ontario's notorious 400-series highways, HEAVY RESCUE: 401 tells the stories of heavy recovery operators who fight to clear wrecks, flip trucks, and keep drivers moving. Close to half-a-million vehicles travel these highways every day, requiring government and police forces to depend on the experienced men and women of Canada's towing industry – ready to work just inches from open lanes and speeding traffic – when disaster strikes.
