This is what happens when you have a adult movie cast trying to do a movie with a plot. You can tell who was paid extra to go topless and who wasn't. So there's this immortal vampire Empress of China who leads a cult of subordinate vampires. The Secretary of Defense wants to recruit her as a secret agent, but trying to stop him is a Von Helsing (not a Van Helsing, because that would have required someone to do research) and a psychic.
The problem is the lead actress... you can barely understand what she is saying and her voice is kind of goofy... But she was willing to do nude scenes, which is what I suspect the director had in mind.
OH, yes. And musical numbers. It has musical numbers. Need I say more. Fake CGI Blood spurts. Cars driving against green screen backgrounds. The beginning of the movie looks like it was competently made, but then the later parts got cheap and kind of silly. You know, like they ran out of money halfway through.
