When Ti Lung and David Chiang left Shaw Brothers, they returned a year later after learning directing and defied their former studio heroics making films with social leanings. Directed by Ti, The Young Rebel is one such film. Fatherless as a child, Hsiang (Chiang) supports his mother. When gangsters kill his mother, he kills in revenge. Unlike his swordplay heroes, Hsiang admits guilt, expresses sorrow and is imprisoned

Kung and Kin's rivalry goes way back to the seventies when they fought over the same girl, who eventually became Kung's wife. Now they run competing phone stores right across from each other on Mongkok's busiest street, and stretch their minds trying to outdo each other with crazy promotions.
