Eva Braun takes inspiration from the actual sex scandals in the Italian Parliament and the 120 Days of Sodoma by Marquis De Sade. This mix create a grotesque journey through power, sex and will of people who does everything to be successful. Pier is a powerful and important Mogul who keeps the power in his country. Elegant, ironical and well educated, he has a bizarre sexual instinct which is satisfied by her mistress, Romy, who collect people, men and women (musicians, directors, writers and businessmen) which agree to satisfy his weird fantasies for getting his help to the way to success. Like a Decameron, a group of people in a house meet their pride and greed for power and sex.

A widower and his sons fall in love with Angela (Laura Antonelli), the beautiful housekeeper. Each man uses his particular way to approach and capture the - apparently innocent and naive - young woman, and to see more of her sexy body. But only one of them succeeds in dominating and conquering her.

Ferdinando Cefalù is desperate to marry his cousin, Angela, but he is married to Rosalia and divorce is illegal in Italy. To get around the law, he tries to trick his wife into having an affair so he can catch her and murder her, as he knows he would be given a light sentence for killing an adulterous woman. He persuades a painter to lure his wife into an affair, but Rosalia proves to be more faithful than he expected.
