That cocaine, incidentally, is the key to the movie's plot, which concerns a fierce group of Miami-based Ninjas who get hold of a drug shipment. Their leader intends to sell it in Orlando but somehow -- and, frankly, I never fully understood how -- the Ninjas must do battle with an ethnically diverse rock band called Dragon Sound. The band's members, as it happens, are Tae Kwon-do black belts as well as rock musicians.
