Rage of the Masters

A brother and sister duo must seek revenge after their family is butchered by the local army of Thai kickboxers. As usually happens, however, the two are not strong enough to take on an entire army on their own, so they enlist the help of their enigmatic Uncle. He introduces them to Tiger, a high-kicking chop socky afficionado who once promised his sweet old mother that he would never fight again. But Tiger is sweet on the comely sister, so it may be only a matter of time before he agrees to help - after which much kicking, punching, crushing of bones and other usual martial arts hijinks begin in earnest.
