A one-hour documentary series that chronicles the daunting challenges faced by teams of heavy haulers around the world, as they lift a 1,400-ton submarine over dry land, tow seven floating mansions across the Netherlands, drive a massive WWI artillery gun across southern England, and much more. These engineers take epic journeys over land, sea, and air as they transport monstrous structures to new locations, often against strict deadlines. It's big moves, big risks, and big stress.
