Barbarie Carnicera (2004)

Three innocent friends, on the advice of one of them, go to the isolated home of a strange medium. He performs some terrifying satanic rituals that trigger a series of strange events—including his own disappearance—and cause the dead to rise from their graves in a nearby cemetery, much to the astonishment of the three. Terrified, they try to flee, but one by one they fall and are devoured by the zombies.
