Twenty years ago, Judge Gu Zhengyuan "accidentally" fell to his death from the twelfth floor. The police closed the case and the real culprit was at large.
Twenty years later, his daughter Gu Nian walked into a "City of Justice" full of cameras - a reality show called "Ultimate Trial" was being broadcast live here: Twelve jurors will decide the life and death of the silent murderer of his wife, and must vote unanimously to be convicted.
Eleven jurors voted guilty.
Only the ninth seat remains.
Gu Nian was silent. What she wanted to try was never the wife-killer - but the three people sitting across from her at the moment: the retired policeman who concealed evidence, the female secretary who passed on the hush money, and the father-killer who bribed the judicial system and is now a philanthropic entrepreneur.
1,876 Cameras, closed for twelve days, a trial watched by the whole people.
When the pressure to vote increases, when the truth gradually emerges under high pressure - who is the real sinner?
