A cross-provincial theft case in Niutun County is about to be closed, but Sun Cheng, a grassroots criminal police officer, encounters Hou Liangping from the east of the Han Dynasty trying to steal his credit. Hou Liangping relied on the power of the Zhong family and looked ugly; behind him, Han Fei received much attention because he was a relative of Sun Cheng's fiancée. A seemingly ordinary arrest operation conceals a power game, and Han Fei's mysterious background makes the situation even more confusing.
