Pursuit of the Murder Case

Case One, "Murder in the Riverside Fog": A man's body is found in the Sanshui River. Though he clearly didn't kill the victim, after being suspected and then released, he turns himself in to the police. Case Two, "The Mantis": On a rainy autumn night, two men drive to an abandoned farm on the outskirts of town to dig up a body. A third man watches them from the darkness. The killer is one of the three. Case Three, "The Mountain Monster": After graduating from the police academy with outstanding grades, Zang Jinshi unexpectedly gives up a promising future and returns to the small county where he was born. He only wants to find out whether a monster really lives in Lingzhu Mountain, and whether that creature has anything to do with his parents' deaths.
