In Wales, haulier Ian gears himself up for a major cross-country mega-move through the rural Welsh countryside. He's tasked with moving a redundant industrial inlet valve that's been signed off as scrap metal. Ian and his cargo require a police escort at the front and his support driver Anthony at the rear. Ian's controlling a total combined weight of around 100 tonnes, so the rugged Welsh terrain is sure to test his truck to the max.As the team head off, the rural roads soon throw up a number of difficulties. There's an exceptionally slender stone bridge, barely any wider than the width of the load to navigate. And there's little let up when Ian must master a turn of almost 180 degrees where every angle needs to be absolutely accurate!In Hull, mega mover Steve is in charge of shifting a 38-tonne screener, a clever contraption used to sift and sort all types of construction waste. Backed up by long-time colleague Carl, Steve uses a control pad to manoeuvre the 38 tonner onto his trailer. But just as he begins rolling the trailer's neck back into place, Carl spots a serious snag. The edge of the screener is sat too close to the neck of the trailer and transporting the cargo in this position would risk sinking the entire shipment. It takes some clever problem solving to get the payload on the move.However, just after they set off, Carl spots another serious obstacle to a smooth escape – a work crew are doing roadworks on Steve's only exit route. Could this shipment be scuppered before it's even started?
