Jiang Yan, who was once a top criminal defense lawyer, lost an unjust case and his wife committed suicide. After five years of silence, when he was publicly humiliated and knelt down in court, he produced evidence to accuse prosecutor Lu Zhao's father, Lu Shiming, of being the real culprit. As the testimony of forensic doctor Shen Xiao and the recording of former detective Lin Wantang emerged, a storm swept across the judiciary, the media and the shady world. Lu Zhao was torn between faith and blood, and the real crime was far deeper than a murder case.
