The cinema world is filled with all sorts of vampires; the best by far are those hyper-sexed bloodsuckers who prey upon comely ladies and tend to latch upon their toothsome victims while the distressed damsels are in a state of arousing undress. The fanged gentlemen of Graveyard Shift (1987) are night prowlers on a dual mission. Not only do these slaves to appetite crave the joy juice of a pulsating pulmonary, they also hanker for hooter-swinging doses of hard-humping hanky-panky. Shift sets its sights on a quartet of mouth-watering mamas, all of whom wave their mammaries. A lucky few ride Dracula dong in the comforts of a cozy coffin.
