Vampires: Los Muertos (2002)

In Mexico, another vampire slayer, Derek Bliss, 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. 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.
