Strange cases have occurred one after another in Hong Kong City, and the death methods of the deceased are exactly the same as the killing methods of monsters in Western mythology. Chen Mo, a former detective from the crime team, opened a private detective agency after leaving his job due to an old case, and was accidentally involved in these bizarre incidents. Without the blessing of superpowers, he relies on his keen observation, years of experience in handling cases and familiarity with the underground rules of Hong Kong City to deal with the Western fantasy creatures hidden in the dark. From a nightclub infested by vampire bats, to a deserted village infested with werewolves, to a strange curse cast by a witch, Chen Mo is reeling from dangers and crises. Not only must he uncover the truth of the case, he must also protect the people of the port city, and he must also face the shocking secrets related to the Western fantasy forces behind the old case.
