Cemetery of Terror(Cementerio del terror)

A professor suspects that a vicious killer may have discovered a way to return from the grave and continue his violent spree. His fears are proved true when a group of teenagers decide to pull a Halloween prank by stealing the killer's body from the morgue. When the teens recite an incantation from an old magic book over the corpse, it begins to come back to life, along with all of the bodies from the nearby cemetery.
