A satire on the American film "The Exorcist," but with an Italian twist.
There's a new girl in school, Angela, the Headmaster's neice. Every male will try to seduce her, even her uncle. Meanwhile she will drive the philosophy's teacher mad and her best friend Irma will have a good time with the classmates. Will they get the grades?
A bankrupt Italian count commit suicide and one of his creditors takes over his family villa but he allows the widow, the mother, and the three adult sisters to stay on. The creditor is a wealthy businessman, but also basically an uncouth peasant (who fancies himself an opera singer). Still, the dimwitted, sex-crazed sisters try to seduce both him and his shy, virginal son who accompanies him.
