The Bad Kids

In the summer of 2005, a meeting takes place at the middle school of a small seaside town ahead of summer vacation.

Zhang Dongsheng looks guilty as he is questioned by the police. The three kids decide to remind the murderer about what they know, and send a warning letter.

Zhu Chaoyang takes advantage of Zhang Dongsheng's carelessness and plants the warning letter; Zhu Jingjing convinces Pu Pu to stop bullying her.

Zhang Dongsheng confirms that the children have video evidence of the crime after following the trail of the warning letter.

Wang Yao visits Zhu Chaoyang's home, and Zhu flees in fear that he knows he was responsible for the death of his daughter.

Wang Yao is desperate to find out the truth, and will stop at nothing; Yan Liang goes to the secret meeting place and finds Lao Chen waiting for her.
