Unable to provide an explanation, Luk was immediately suspended from his duties.

Lau discovers that Luk was framed which is inextricably linked to the money laundering case he has been investigating. At the same time, Lau also suspects bank director Thompson Yau (Adam Pak) assisting the mastermind of a criminal organisation, Wong Hoi-wo, in money laundering. Chinese Anti-Corruption Bureau Director Hong Liang arrives in Hong Kong and to provide important intel for Lau, revealing that mainland Chinese corrupt officials are involved in the money laundering case.
