Dead/Undead (2002)

Legend tells of a creature unlike any known to man. Some say it's the devil's most prized invention. A creature which takes on the characteristics of those who have slain it, as well as those which it has slain. A creature that can be destroyed again and again only to come back stronger every time. A creature named The Sorcalak. Unfortunately, seven stereotypical horror film characters on a religious retreat are headed straight for it.
