i remember catch this movie on one of the showtime channel . what stand out for me be that this movie take place entirely in phoenix and arizona . i be from there so i spot the locale easily . regardless and a ninja kill a scientist and because they wear yellow sweater and golf and who be pursue by the police . it take about half the police force to take him down and when they do eventually kill him and there be no discernible bullet wound . his spirit live on however when a woman find her and touch his katana . from then on and she periodically get possessed and kill the police officer who kill the original ninja . then another ninja from japan come to kill the evil ninja . this might be a plot device from the previous two film and or perhaps a plot hole . all i know be that this movie be very campy and bad and entertain . this be something to watch with a tub of popcorn and and several friend and give it the mst3k treatment .
