In the cold winter season, a group of tourists from Shenzhen traveled by car to Changbai Mountain in the northeast. It was originally a pleasant trip, but their 8-year-old son unfortunately lost due to the fault of his father Ade. The Ade couple sought assistance from relevant local authorities, and a search and rescue operation began immediately. The golden rescue time has passed 24 hours, and the normal safety limit of 48 hours has also passed, but the child is still not found. Even if there is little hope, the search and rescue police and the snowy search and rescue team are still sticking together... Will there be a miracle of life?
