Thirty years ago, teenagers from Zhechao Welfare Institution were sent to Tingguang Factory. After the fire, the records stated that nine people died and 46 people were awaiting resettlement. However, review prosecutor Yuan Zhen dug up the remains of an uncounted teenager in an abandoned cable trench: the teeth were only between fifteen and seventeen years old, but all the people on the accident roster were "adults." The first age correction form, borrowed work badges, executed executions, and "dead people" who were still alive appeared one after another. Yuan Zhen gradually discovered that someone had written all minors in large letters; thirty years later, someone else used the same set of paper loopholes to make profits, control identities, and burn evidence. With each name she uncovered, she had to answer a harder question: Could true age change a verdict? Will correcting the identity once again take away the life the person has already lived? And the second fire is burning along the recovered files.
