Plot summary
Achille De Bellis is a wealthy manager of a large hotel chain, property of the family of his wife Gigliola for generations.
While Gigliola is struggling with the preparations for their 25th wedding anniversary party, Achille fires a chronically depressed hotel maid (Annarita) for the theft of an expensive laptop. Annarita's son Orfeo, a 24 year old waiter stressed by his mother's depressive crises and by their unhappy economic situation, pleads with Achille to no avail.
Embittered and angered by Achille's indifference to his plight, the young waiter decides to ruin Achille, he follows him to a secluded place outside the city, and he takes photos of Achille with his young and attractive sister-in-law Ramona. Orfeo persecutes the two lovers through intimidation and small acts of vandalism, until he openly threatens Achille to reveal his affair. Meanwhile, following a traffic accident, Orfeo meets Cecilia, with whom he quickly falls in love. Orfeo, unaware that Cecilia is Achille's daughter, crashes Achille and Gigliola's anniversary party, distributing compromising photos of Achille and Ramona.
