The day Liao was discharged from prison with his maimed right hand was also the day Nan was forced to retire. Nan will no longer be the head of CIB, just as Liao will no longer be a pickpocket. Liao wants to find the young pickpocket who called him “Daddy” back then, while Nan misses his daughter badly, who hated him profoundly and was unwilling to forgive him. So the two desperate old fellows start trying to find their last hope.
Our story begins with Junior Detective LIN, who has just been put in charge of a case that appears to be a suicide. Most curiously, the crime scene has many features in common with a scene from a Sherlock Holmes novel. Detective Lin quickly discovers that it is a murder case. Meanwhile, a group of young sleuths supports their detective club president GAO’s dream to win a writing contest. The three club members, psychologist ZHONG, social worker WEN, and pharmacist ZHANG, each harbor a hidden secret. GAO could never have expected that he would become implicated as the killer in an actual murder case! As Detective LIN delves deeper into his case, a series of seemingly unrelated events all end up pointing towards the club members.
