The Mystery of the Puppet Master

A serial murder case broke out in Binhai City. The victims died in strange ways and were arranged into "puppet" postures, which is exactly the same as the "Puppet Master" unsolved case twenty years ago. Interpol captain Lu Zhiyuan restarts the investigation and reunites with criminal psychology consultant Shen Qingyin - she is the daughter of police officer Shen Yuan who died in the "Puppet Master" case twenty years ago. The two worked together to investigate, but in the process, they uncovered a series of truths that subverted cognition. Shen Qingyin has regarded her father as a hero since she was a child, but during the investigation, she discovered that Shen Yuan was actually the first-generation "Puppet Master" who took away a huge amount of stolen money from the "Black Hawk Society" and wanted to establish a fund to assist victims. In the end, he was betrayed and silenced by his confidant Gao Tian and his accomplice Zhao Yongcheng, and the crime was framed on others. At the same time, Shen Qingyin unexpectedly reunited with her surviving twin brother Shen Mo. The two brothers and sisters, tasked with avenging their father and fulfilling their last wishes, secretly set up a chess game.
