On New Year's Eve, four elite siblings start a brainwave live broadcast to judge Chen Mo, the dying eldest brother on his hospital bed, an "abandoned son" despised by the whole family for thirty years. However, as the memory footage unfolds, what they see instead is an eighteen-year-old boy in the sea of fire of 1995 pushing them ashore one by one, walking alone into the dark, acting as bait with his own body. Only then do they realize that the person they personally sent to the trial platform has a file marked with an S-class secret.
