Bitter and angry, Peter joins the triads along with his pal, and finds new romance with the luminous Maggie Cheung. When given the chance, Peter even uses his new underworld position to threaten his previous boss! But Peter sinks too far into the triad underworld, and soon not even his family can be spared from violence. A harrowing drama that progresses from social critique to triad indictment, My Dear Son runs the full gamut of emotions to deliver a tough and truthful message about the choices we make in life.
