In the play, Zhuang is a complicated and tragic figure. Zhuang was isolated by his classmates at school because he came from a thief's family. Moreover, once someone lost something at school, the students thought it was Zhuang.

Fortunately, there are Lin Zhiyue and two good friends in Zhuang's life, otherwise Zhuang can only live in the dark all his life. However, the identity of a family of thieves also gave Zhuang an unusual mode of thinking. Plus, he is studying law and knows the psychology of criminal suspects like the back of his hand. Therefore, Zhuang wants to use his intelligence to help solve the case.

However, the thieves did not intend to let Zhuang go. Zhuang also wants to find out the truth about his father's disappearance. So, Zhuang used Ding to make a fire and took the initiative to enter the game. However, Zhuang joined the gang of thieves only to find out the truth about his father's disappearance and didn't want to go along with it. Therefore, he acted in secret without telling Lincoln Lo.

In the end, Zhuang succeeded in undercover and helped solve the case successfully. At the same time, Zhuanghe also became friends who fought side by side. Since Zhuang found out the truth about his father's disappearance and helped solve the case, why did he end up regretting it? That's because he finally saw his father again, but he lost his father again.

Second, Lincoln Lo.

Lincoln Lo played by Zhang Yi is a considerate, honest, kind and brave policeman. He has been protecting Zhuang from the dark forces in his own way. Although many colleagues found that Zhuang was involved in the theft, Lincoln Lo still firmly believed that Zhuang was definitely not a bad person.

It was the affirmation and appreciation that Zhuang put down his guard and chose to cooperate. In the end, the two successfully solved the case. Lincoln Lo's outstanding performance in this theft case was praised by his superiors. At the same time, in the process of cooperation with Zhuang, she also let go of her obsession with Master.

Third, Liao Shuang

Liao Shuang is Lincoln Lo's right-hand man. She is capable and straightforward, both rigid and flexible, and is good at dealing with disguised enemies. A beautiful and capable policeman like Liao Shuang is sure to make a difference as long as he works hard. As a result, Liao Shuang turned out to be an undercover arranged by a thief gang in the police station. But Liao Shuang was forced to commit crimes for a thief gang. Finally, Liao Shuang took a bullet for Lincoln Lo and died.

Fourth, Zhuang

In the play, Zhuang is a mysterious figure. No one knows whether he is alive or dead, and no one knows why he helped the mysterious man steal things. However, judging from the way Zhuang and Zhuang get along, he is definitely a good father.

Finally, Zhuang appeared again and helped Zhuang get the evidence that the mysterious boss was stolen. However, Zhuang was killed by a group of thieves in order to help Zhuang escape at a critical moment. Therefore, Zhuang's ending is not satisfactory.
