The Vampire Raiders (1988)

The fate of the entire hotel industry is at stake. A group of evil black ninjas have threatened to insinuate themselves into the industry, take over, and transform the operation into something unspeakable. Thank heaven the white ninjas are on hand to save the day. Agnes Chan heads the cast, so we assume she's the "ninja queen." This one isn't a whole lot better than others of its ilk, but at least there's some novelty in the settings.
