Heavy Crime Bureau chief Pau Yu Chat (Kenneth Tsang) sends Lung to go undercover to take Yau's job. After Lung goes undercover, he rises in rank and his paychecks increase.

Later, Julia brings Lung to meet a land developer, Tang Kwok-kiu (Damian Lau). During that time, another murder case comes up.

Another inspector, Shek Chun (Waise Lee), then gathers evidence and is determined to bring Tang to justice.
