Former king of the battlefield Xiao Tianren returns from retirement, only to discover that his parents' deaths were no accident. His enemies hold all the power, and the law has become their shield. He takes up the law as a weapon: by day, he is a top lawyer, defending the innocent with the letter of the law; by night, he dons a ghost mask and uses his fists to send scumbags to their graves. When the rules are no longer fair, he becomes the new rule. In court, he fights with words; under cover of night, his fists show no mercy. He is the Judge, and he deals with injustice in this world.
