Lin Zhongtian, an outstanding police academy student, is recruited by the Thirteenth Bureau after graduation. Only after joining does he discover that the cases handled by the bureau are all bizarre and strange. The Thirteenth Bureau has four members, each with an unusual personality. Director Chen Dongming is a former detective, steady and experienced in criminal investigations. Usually serious and composed, he is actually warm-hearted beneath his cool exterior, and the brains of the entire bureau.
