This is one of the many Golan - Globus made movie. They had series of low budget movies that were pretty entertaining. This is one of it.
For almost no reason at all (At least it's not explained in the movie), a guy comes into a cave looking for a hidden sword. He finds it, and the sword transforms him into a super ninja. He then goes out to a golf course, and kills a couple (Again it's not explained who they were) and gets chased by the cops. Cops shoots him with guns and shot guns, but the ninja guy doesn't die (Again no reason). Then he escapes, and meets a girl (Lucinda Dicky). Then a strange thing happens: The spirit of the sword transfers to the girl, and now the girl becomes the super ninja. Then the possessed girl goes out on the revenge on people that shot the first ninja guy. Now enter Sho Kosugi. He's a ninja too, and seems to know all about what's going on, and shows up at key locations (Again for no reason explained). How would they save the girl from the ninja possession ?
This is movie that's purely made for entertainment. As you can see, the premise of the story suddenly happens, and then just keeps going without any explanation, but you don't care because of Lucinda's physical charm. She's the most beef cake actress I've ever seen. Other supporting actors are pretty good. Whatever the reason, the producers knew what they were doing, because this is an entertaining movie.
It's a good movie, and is recommended for viewing.
