After the Costa Concordia capsized off the island of Giglio in 2012, killing 32 people, the wrecked cruise liner sat half-submerged on its side for over a year before engineers attempted something never done at this scale: righting a 114,500-ton ship where it lay. This film follows senior salvage master Nick Sloane and a team of roughly 800 specialists through the Parbuckling operation, the process of using cables, strand jacks, and underwater platforms to pull the hull upright without breaking it apart. Footage and interviews cover the engineering problems as they arise, from building an artificial seabed to support the wreck's weight to the tension of the actual pull, watched by the world's media from boats offshore. The film explains the physics of the maneuver in plain terms, showing how a single miscalculation could have capsized the ship entirely or sent it to the bottom of the Mediterranean. It closes with the wreck's final journey to be scrapped, closing out one of the largest and most expensive salvage jobs in maritime history.
