Criminal psychologist Li Wei was called into the case to assist, but was shocked to find that the last victim might be herself - because she had been a bystander of the tragedy. When the truth approaches, she must face her deeply buried guilt before the murderer completes the "**Seventh Trial**", otherwise, **everyone will pay the price** Fifteen years ago, a girl died during campus bullying; fifteen years later, her trial began. **
