Antonino Iuorio

A young opera singer is stalked by a deranged fan bent on killing the people associated with her to claim her for himself.

Her name is Mina, but she is called Bambola (doll). Upon the death of her mother, she and her homosexual brother, Flavio, open a pizzeria. A man named Ugo loans Bambola the money, but is then killed in a fight with another one of her boyfriends, Settimio. While visiting Settimio in jail, she meets a sadistic man named Furio, and they begin a relationship.
