In the meantime, William Luk was suspended when model Eva Ng (Stephy Tang) went to Inspector Kenny Ching (Kevin Cheng) of ICAC's Internal Investigation Group L, to file a report against him for accepting a $12M bribe. Lau discovered Luk was set up and whoever framed Luk was connected to his case.
He began to suspect the bank manager Thomson Yau (Adam Pak) was assisting a gangster, Wong Hoi-wo (Patrick Tam) in money laundering activities.
When Director Hong Liang (Ding Haifeng) of China's Anti-Corruption & Bribery Bureau (ACBB) provided Lau with important intelligence, it became clear the money laundering activities were connected to a corrupted Vice-Ministerial Level cadre. To clear his name, William Luk put everything on the line.
