Filmmaker Natalie Hewit follows the everyday people battling in the most extreme environment on Earth to move Halley VI, a vital polar research station. Britain's state-of-the-art Antarctic research base Halley VI is in trouble. Built on the Brunt Ice Shelf, it sits atop a massive slab of ice that extends far beyond the Antarctic shoreline. But the ice is breaking apart and just 6km from the station is a ginormous crevasse, which threatens to separate Halley from the rest of the continent, setting the £28 million base adrift on a massive iceberg. So Halley needs to move. But this is probably the toughest moving job on Earth, and the team of 90 who have been tasked with the mission aren't just architectural or engineering experts. They are plumbers, mechanics and farmers from across the UK and beyond - ordinary men and women on an extraordinary adventure. Their practical skills will be what makes or breaks this move.
