Qin Chuan originally had a dream to show his talents in the criminal police team, but Han Jingdong transferred him to the pre-trial department.This made him full of confusion and uneasiness, so he went to Ye Maosheng to talk to him overnight.Ye Maosheng was reviewing for the exam, and Zhao Fei suddenly called Qin Chuan for help. He and Wei Ning were arresting the suspect at the southern suburbs airport.Although Qin Chuan wanted Ye Maosheng to go with him, considering his studies, he still let him stay at home while he and Xiao Qingdong rushed to the provincial capital overnight.

However, Ye Maosheng did not follow Qin Chuan's advice.When he went downstairs to relax, he accidentally witnessed the car thieves and rushed forward without hesitation.The car thief resisted desperately and the two struggled with each other.In desperation, the car thief fired three shots and then drove away.Ye Maosheng was seriously injured, but he still struggled to chase for a few steps, and finally fell in a pool of blood.

After Wei Ning learned about this, he quickly woke up Qin Chuan.Qin Chuan and Xiao Qingdong rushed back to Hechang anxiously, only to see Ye Maosheng succumbed to his injuries.Qin Chuan was devastated, as if he had lost his own brother.

The police quickly launched an investigation, found witnesses, and discovered the suspect's abandoned vehicle in the No. 7 family area.Qin Chuan rushed to the scene immediately and learned that the suspect's name was Niu Yuguo, a prisoner released from a labor camp.Qin Chuan, Hu Bing and others quickly launched an arrest operation, but Niu Yuguo took the opportunity to escape.Qin Chuan chased after him and finally forced Niu Yuguo to surrender in a snowy field.However, when Qin Chuan thought of Ye Maosheng who died tragically, he couldn't help but raise his gun.Fortunately, Hu Bing arrived in time to stop him.

Qin Chuan and Xiao Qingdong came to Ye Maosheng's grave to mourn. Recalling the time they spent with Ye Maosheng, Qin Chuan couldn't help crying.He came to Ye Maosheng's home and saw Ye Maosheng's suicide note to Li Wen, and felt even more sad.After Ye Haiping learned the news of his father's death, he cried sadly.

Qin Chuan came to the pre-trial department to report, only to find that the place was in chaos.Section Chief Tan Mulin handed him the backlog of files, hoping that he could lead the pre-trial department to normalcy.However, the murder of Ye Maosheng encountered many difficulties.The procuratorate returned the case because Ye Maosheng did not perform an autopsy, which made Qin Chuan furious.He ran around asking for help and finally submitted conclusive evidence to the court and successfully sentenced Niu Yuguo to death.

Li Wen was transferred to work in the Legal Affairs Department of Xucheng City Bureau, and she was undecided whether to go.Qin Chuan and He Qinglian encouraged her to look forward and agreed to help take care of Ye Haiping.Li Wen finally decided to leave the Qinchuan family to work in Xucheng. Ye Haiping was very sad when he learned about it.Qin Chuan comforted her and promised to let Li Wen come back to see her at any time.

Qin Chuan began to deal with the backlog of cases in the pre-trial department. He called a meeting with all staff and assigned cases to everyone.He personally went to the procuratorate to understand the situation, but was treated coldly by prosecutor Chai Yunping.
