Horror Rises from the Tomb (El Espanto Surge de la Tumba)

In medieval France, a warlock is beheaded and his wife executed for witchcraft. Centuries later, a group of friends discovers his buried head. The head reanimates, possessing the living to perform ritual sacrifices and seek out the rest of its body. The group must fight for survival against the warlock's sinister supernatural power and his growing army of zombies as he leaves a trail of terror and decapitation in his quest to be whole again.
