Plot:
Procuratorial technicians represented by Lin Yuanhao and Lin Lan use advanced professional and technical means to assist prosecutors in breaking through the bottleneck of difficult cases and conquering "zero confession" cases. The confusing truth behind the field dismemberment case, the interest groups involved in the foggy "national treasure theft case", and the unknown filth and evil hidden behind the glamorous appearance. Many old cases were solved one by one until the truth of Lin Lan's father's accidental death was finally revealed. More than 30 years of love, hatred, and repeated struggles between justice and evil interpret the important role of the procuratorate in the construction of a rule of law in China from a new perspective.
