A Dragon Lady (Mari Honjo) - evil of course, and seemingly unable to open her mouth much when she speaks - has had three martial arts fighters injected with a serum to turn them into zombie killing machines (Michael Chong, Ronald Marchini and Joshua Johnson).
They wipe out a mafia boss' usual assassin force so he had no choice but to hire them instead to do the killings he desires. What can the police do about this?
The film makes no sense (well that is a surprise). The bizarre antics and performances, plus a lot of violence make the film very watchable in the "so bad it's good" category.
