Sue risked her life to send crime documentary materials to the provincial capital, which recorded in detail the whole process of extraordinarily brilliant crimes. On the way to the provincial capital, Xiao tried to kill Sue, but failed. At this point, Guo Shouyi already knew that his affair with Zhao could no longer be concealed. He knew that he had no face to face all the people, so he thought of a way to get rid of crime.
Many workers were trapped in the tunnel collapse accident. Guo Shouyi tried his best to save the workers, because he knew he was guilty, and he would save the workers at the expense of his own life, and finally died in the line of duty. Guo Shouyi's wife came to the public security bureau after learning that her husband was killed in the line of duty and confessed her crime.
At this time, the public security department has mastered all the criminal evidence of Zhao, so it issued a wanted order to the whole city to hunt down Zhao. Zhao finally fell into the net after being chased by everyone and was finally punished by law. However, Zhao's accomplice, Liang Xinghao, did not escape the legal sanctions. He was arrested by China police abroad. As a defender of justice and law, Zheng Yiran is welcomed and loved by the people of the whole city.
