Rescue workers describe the moments when disaster leaves almost no margin for survival. The film moves between four true stories: climbers stranded at 8,600 metres in Everest's death zone, sailors pulled from a sinking ship, a driver cut free from a burning car, and a man found alive after 62 hours trapped inside a vessel resting on the ocean floor. Interviews with the rescuers and survivors sit alongside reenactments and archival footage of the operations themselves, tracing the decisions made in the first minutes after something goes wrong and the physical toll of working at altitude, underwater, or against fire. Rather than treating each rescue as a stunt, the film lingers on the logistics: the oxygen calculations on the mountain, the search patterns at sea, the seconds available before a car fire becomes unsurvivable. The throughline is the same in every case, that professional rescuers accept extreme personal risk as the baseline cost of the job, and the film lets that fact sit without embellishing it.
