The Last Mystery of the 20Th Century

On December 31, 1999, a mysterious fire in the city archives nearly destroyed all the files on unsolved cases. During this fire, a file on the "12.17 Dismemberment Case" was "happily" brought out by a mysterious night watchman. Most of the police officers who handled the old cases 20 years ago have passed away or been transferred, and all evidence pointing to the murderer has been destroyed over the years. But the rescued file recorded a heart-stopping detail - the murderer left something at the scene that absolutely shouldn't be there. That thing does not belong to the 20th century. The person responsible for re-investigating the case is the son of the policeman who handled the case and is now the captain of the criminal investigation team. What he has to face is not only the gap of time, but also the obstruction and pressure from all forces. A secret that has been silent for twenty years involves the rise and fall of a prominent family, and also opens the wounds under the bright appearance of a city. While everyone is toasting to the new century, someone is trying to keep the truth in the 20th century forever. And what he wants to do is to let the dust-laden truth come to light again before the bell of the new century rings.
