The Young Tiger.

A spoilt rich kid turns up at a fu school to show off, but he gets clobbered by the boastful Little Tiger, who is later framed for the kid's murder when a gang of blackmailers make an example of him. The police allow Tiger to escape, in order to find the real culprits. Tiger hides at his girlfriend's place, but a model she works with does some whoring on the side for the blackmailer, and so the crooks are onto his trail...
