Six people lost contact with each other at the "Absolute Zero" scientific research station at 78° north latitude. Only six chairs and five sets of footprints were left at the scene. Cryogenics experts parachuted in to investigate, only to find that the temperature of the seat back was 5°C higher than the seat surface, and the heartbeat was counting down on the intercom. The ECMO at -80°C in the cold storage is still running, and there is a note floating in the blue antifreeze: -273.15°C, the lie is gone. When heat becomes a murderous weapon, the only way out is to return body temperature to zero.
