 Semi-sequel to  John Carpenter s Vampires  (qv). In Mexico, another vampire slayer, Derek Bliss (Jon Bon Jovi), is hired by a shady priest and aided by a group of fellow slayers in finding a large nest of  suckers  and their powerful leader, a vampire princess (Arly Jover). She is seeking a legendary black crucifix -- the same crucifix used unsuccessfully in the first movie to perform a ritual which will enable vampires to walk in sunlight and be invulnerable.
