Born in a small town in the countryside surrounding Pistoia, Adriana is an attractive young girl who counts on using her looks to go places in the entertainment business in Rome. Moving to the capital, she works first of all in a hairdressing salon, then in a small cinema where she manages to get a job working in fancy dress. Meantime, she socializes with young men of the upper middle classes, who take her to parties and out on the town with the sole aim of taking advantage of her. Adriana knows their game, but plays along. In the meantime, she meets an agent called Cianfanna, a modest money-grubber who introduces her to a journalist friend of his so he can write an article on her. Having thus launched her career in advertising, Adriana decides to go home to visit her parents. Once home, however, she is distraught to learn of the death of her sister. Returning to Rome, she takes acting lessons, but during one lesson she suddenly faints: she is pregnant, with no idea of who the father of her child is. The days go by and Adriana tries to forget about her pregnancy, while sleeping with an increasingly long list of lovers. And yet, despite the fact these encounters are often less than enjoyable, at one point she actually falls in love: his name is Antonio and he's a decent young man from a respectable family, but still in love with a former girlfriend he is unable to forget…
