Detective vs. Sleuths

Hong Kong is rocked by multiple gruesome murders whose victims are all suspects who have got away in previous cases. The vigilantes claim themselves “the Sleuths” to taunt the police. In response, the police form a special task force.

Once a brilliant detective, Lee Jun has been expelled from the force after a mental breakdown. To prove himself a capable detective, Lee Jun joins the task force at the request of Lieutenant Inspector, Chan Yee. They must race against time to solve all the new and cold cases in order to hunt down the Sleuths.
