Xiao is the only survivor and escapes, with the help of Junko who seems slightly conflicted - probably the only depth or shade of grey in this film - to learn ninja fighting skills himself. With three friends he returns to challenge the ninjas in a final showdown against the five elements of ninja: gold, wood, water, fire and earth...
Don't expect a huge amount of story here, the film is about 95% fighting, but that's really what you want from a film like this. The action is often rather over the top with various wire-fu and mysterious bending of the laws of physics. There is also quite a lot of literal destruction of the human form. An amazing film full of bizarre ninja weapons, men in white capes and Junko in her leather and fishnets outfit.
