Lin Chen, a college student from an ordinary working-class family, is introverted and has excellent grades. He has been secretly in love with the school belle Su Wan for two years. He thought he would spend his college years quietly like this, until after a club party, Su Wan was found dead tragically in a remote corner of the campus.
All evidence points to Lin Chen - fibers from his coat appeared at the scene, his mobile phone location coincided with the time of the crime, and someone even "witnessed" him having an argument with Su Wan. Under the double attack of public opinion and evidence, this young man who had never had any criminal record went into the abyss.
