This is a world where "legal suspense and psychic powers" are deeply combined. The protagonist, Shen Mo, is a down-and-out lawyer who graduated from law school. He specializes in providing "soul evidence litigation" for unsolved cases, unresolved cases and unjust deaths: through his psychic ability, he invites the souls of the deceased to testify in court and confront the defendants on the spot. The court must accept this kind of evidence, but it must meet three strict conditions: the soul of the deceased must be within 50 meters before it can be summoned; the deceased must have a complete and clear memory of his death; the defendant must have at least one physical evidence of direct contact with the deceased. In the eyes of ordinary people, this is the behavior of a lunatic, but for Shen Mo, this is his only way to survive.
