2016, Heihe City. In order to win the "perfect attendance award", the online ride-hailing driver **Fan Datou** found a bag of body parts in the "blind box" in the trunk when he was driving a celebrity anchor!
This pull not only triggered a hot search in Heihe City, but also started a series of mysterious cases spanning 18 years.
Former criminal police captain Lu Jiujin, a security supervisor who talked about "lying flat" but built eight-pack abs in the gym, was forced to return to the world. He discovered that the bone age of this broken corpse was exactly the same as that of the abandoned baby 18 years ago who was "played as a ball by the rich second generation"!
On one side is the reopening of old cases after the upgrade of DNA technology, and on the other side is the tragedy of parenting in the abyss of human nature.
When the truth was peeled away like an onion, everyone's defenses were broken: it turned out that the murderer was no one else, but the "long autumn" in each of us.
