When the father and son spend a day watching a horse race together, Tong Chi-Ko meets Tung Yat-Tsun (Ron Ng), a veterinarian and the nephew of the head of an affluent corporation.

Her younger son, Tung Yat-Chiu (Vin Choi), ends up being a selfish troublemaker and her niece, Sung Ka-Yee (Shirley Yeung), reveals herself to be manipulative, spiteful, and two-faced.

Tong Chi-Ko's father commits suicide after mistakenly believing his wife and daughter left him because he was unwilling to stop gambling and unable to get out of debt.

Chi-Ko loses his licence to practice law, but is able to find work as a legal advisor for Nicholas, Tung Chin-Long's fashion company, with help from Yat-Tsun.

Soon Chi-Ko finds out the true identity of Wing and is recruited by Madam Wong, to go undercover and reveal Gam-Chi and Chin-Long's suspected bookkeeping and underground firearms business.
