On Nantucket Island in Massachusetts, we follow Jerry Matyiko and Joe Jakubik attempt to move Sankaty Head Lighthouse away from the crumbling cliff edge. The historic landmark weighs over 500-tons and is over 90ft tall. Can the team keep it upright as it moves along a unique rail track inland? In Malmberg, Sweden we follow 25-year old house mover Andreas Martensson relocate the homes in a mining town. With the mine underneath the town collapsing, Andreas is locked in a race against time to move the buildings to safety before the arctic winter strikes.
