In Manchester, Sam aka Hiab princess, has been tasked with delivering three huge shipping containers to a remote farm near Spalding with a colleague. Her first step is getting a high cube container loaded onto her lorry at a local yard. Payload primed, Sam sets off in the hope of steering clear of any traffic snarl ups, but an unexpected diversion off the A52 soon presents her with some serious obstacles to dodge.

Arriving at her destination's remote location - a slender entrance at the end of a dirt track - means Sam and her chunky truck have a mega tight squeeze to master. And when her colleague arrives with the two additional containers, Sam's clear directions are essential to steer him safely down the road in reverse. Getting this delivery done and dusted will require meticulous manoeuvring so the pressure is on, as Sam primes herself for a power pickup!

At Droitwich Spa Marina in Birmingham, Mark's in charge of a massive move of a 57-foot-long canal boat to Mercia Marina. It's recently been purchased by a couple who plan to make it their new home so this precious payload will need some careful handling. To ensure the costly cargo remains stable during its journey, it must be perfectly positioned on the trailer. Once Mark and the team have the colossal consignment loaded, he's ready to hit the road.

But just as he reaches the outskirts of Derby, he hits some choppy water when a tight residential road, restricted by vehicles parked to the side presents him with an extremely narrow pathway to navigate. At the marina, the boat's new owners are keeping a close eye on proceedings, so it's all on Mark to ensure this maritime manoeuvre goes precisely to plan!

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?
