Modern criminal policeman Zhu Chen is transformed into the useless prince of the Ming Dynasty. He relies on modern criminal investigation techniques such as fingerprint identification and on-site reconstruction to repeatedly solve bizarre cases in the capital. From establishing his power in the prince's palace to entering the court, he formed alliances with partners such as Shen Xingci, who is proficient in law, and Liu Ruoxi, who has unique skills. He not only wants to solve unsolved cases, but also single-handedly fights against the corrupt judicial system and promotes a judicial reform storm that has spanned ancient and modern times.
