Since dropping out from the medical school, Lau Mack has been living a humble but contented life, running a small clinic in a shabby area, treating local inhabitants and poor prostitutes working there. One night, he escorts an injured gun robber to the government hospital, where he unexpectedly meets his old friend from college time, Dr. Jaw, now a reputed surgeon with an aspiration for senior management. To Jaw's bitter surprise, he finds himself outshone by Lau's medical talent and kindness to patients. Jaw is however determined to speed up his career ascent at the expense of Lau. His plots work perfectly, until an accident delivers his life to the mercy of Lau.
