In the early years of the Republic of China, people often went missing on both sides of the Lu River.
Among these missing people, there are young ladies from wealthy families as well as ordinary people.
The missing person this time is a Japanese girl.
The Pucheng Police Department sent a capable detective, Lu Jianguo, to make an unannounced visit to the Luhe area.
Just when the case was about to be solved, the Japanese invaders' artillery fire caused the case to fail.
Many years later, the detective repeatedly performed extraordinary feats in special times.
