Descargar Exorcism (1975)

She promptly begins exhibiting the standard symptoms - curses, vomiting, and even twisting the heads of a few people 180 degrees. Naschy plays the village priest summoned to perform the rites of exorcism, and must fend off the possessed's lewd advances before casting the evil spirit out of her body.—Ørnås
