Inhabitants of the planet Drakulon use a synthetic concoction to quench their thirst for blood. When Vampirella's (Soto) stepfather is murdered by rebels, led by Vlad Tepes (Daltrey), she must pursue them to earth to get justice. There she finds two opposing forces--the vampires led by Tepes and a paramilitary group led by Adam Van Helsing (Paul), who's out to cleanse the planet of the interlopers. But it's Vampirella who wants a final confrontation with Tepes (in Las Vegas, no less).
