In the small town of Qingchuan, which is shrouded in thick fog all year round, a bizarre secret room murder suddenly occurred. Female college student Su Qing died tragically in the dormitory, leaving only the words "Man in the Mist" as her last words. Interpol Lin Shen was ordered to conduct a thorough investigation and unexpectedly uncovered an old case from the Republic of China that had been buried for a hundred years. Su Qing was silenced for investigating the unjust case of her ancestors and uncovering the centuries-old blood debt of the family. Lin Shen withstood the pressure from all sides, uncovered the conspiracy in the secret room, uncovered the real culprit and the protective umbrella behind the scenes, broke through the layers of fog, let the truth of the centuries-old injustice come to light, and defended the belated justice.
