Amityville II: The Possession

When The Montellis, an Italian-American family, move into the not-yet notorious home, it's not long before rebellious teenage son Sonny (JACK MAGNER) takes to seducing his sister (Diane Franklin) and slaughtering the entire family. Investigation by the authorities points to the boy's demonic possession, which is later evidenced by a grisly EXORCIST-inspired physical transformation. (officiële tekst van distribiteur)
