The snow outside the court was colder than the charges. Former prosecutor Shen Zhao puts on his defense robe again and joins forces with idealistic lawyer Jiang Yanzhi to uncover a cover-up case of the death of a young girl. When the truth is crushed by traffic and testimonies are written by powerful people, silent interns, self-destructive forensic doctors, and former victims who manipulate public opinion are all involved in this smokeless trial. They are not fighting to win, they are fighting to make the law worthy of those who no longer have a voice.
