In the third part of the series, we find the Hung Hing duo -- Chicken (Jordan Chan) and Nam (Dior Cheng) -- in a troubled state; Chicken has just committed murder, and Nam is distraught over comatose girlfriend Smartie (Gigi Lai). In time, she awakens with amnesia, and Chicken returns after being on the run. Meanwhile, Nam's boss gives him more to do, but it's the new Tung Sing gang slowly taking over their territory that has the boys busy.
