Abatjour 1 (1988)

Camilla, daughter of fallen noble, at the invitation of her childhood friend Eliana returns to the small town where the two have grown up, to recover all her family goods with her dark charm. Nothing could be easier for a woman without scruples like her: everyone will fall at his feet in the illusion of obtaining, in addition to his graces, also his heart. She gets a relationship with her friend's father, Antonio and marries him and even seduces her fiancé.
