Revenge of the Ninja is an entertaining martial arts actioner, following up Enter the Ninja (1981) but lacking that film’s name players and Far East locale.
After a brief intro set in Japan, where Cho Osaki (Sho Kosugi) witnesses most of his family wiped out by black-clad ninjas, action shifts to an unidentified US locale (filmed in Salt Lake City) six years later. Osaki, with his surviving child and its grandma, runs a gallery featuring imported Japanese dolls, which unbeknownst to him is a front for heroin smuggling run by his pal Braden (Arthur Roberts). Braden is involved with an unscrupulous US mobster Caifano (Mario Gallo).
Revenge occurs when Braden kills grannie, kidnaps the child Kane (Kane Kosugi) and later kills Osaki’s best friend, martial arts expert Dave Hatcher (Keith Vitali). Fine fight choreography by Kosugi, including fast and often funny moves by him, keeps the film cooking.
