The discovery of a bizarre corpse exposes a tangled criminal network. Captain Xu Muchen and forensic examiner Lin Weiran team up to investigate what seems like an ordinary case, only to stumble upon an old murder and an unsolved serial killing. As the investigation deepens, they uncover a vast transnational crime syndicate involved in underground dealings, gang activity, collusion between officials and businesspeople, and possibly even members of the police leadership.
