Luiza is an architect who just got out of a ruinous relationship. Gabriel is a biologist and he has finished a long marriage with divorce. When they both meet, chances that they can do well together are not that big. But they will try to, even if their friends Barata (a convict bachelor totally skeptical when it comes to love) and Marta (a mathematic analyst who wishes that human relations were just as exact as numbers are) think otherwise.

Evelin, 13, is pregnant from a 22-year-old who recently left the drug trade. Luana, 15 years old, declares that she planned her pregnancy, as she wanted to have a child of her own. Edilene, 14 years old, is expecting Alex's child, who also got her neighbor Joice pregnant. Over the course of a year, the daily lives of these three young women are followed.

Jessica, Sabrina and Daiane have dreams, just like all young people of any social class or place in the world. They live in a low-income neighbourhood in the periphery of Rio de Janeiro and find in prostitution a way to survive and satisfy their consumer desires. However, even faced with the trials of absolute uncertainty and lack of hope, Jessica, Sabrina and Daiane insist on loving, having fun and planning their future.

Fifteen year ago, Carlos went to the cinema to meet Júlia, his university colleague with whom he was in love. She never showed up. Carlos was left waiting in the lobby alone. While he waits, something happens which will change his life. A scene, an encounter, an unfinished sentence... Something insignificant, but which will determine the character's life. Fifteen years later, we follow three completely different versions of Carlos's life. In one, he is a man divided between the stability of a secure life in a lukewarm marriage, and the growing desire to live a great love affair. In the second, he is homosexual and places passion above all else. In the third possible life, Carlos is a man who hasn't yet discovered love, and lives through successive disastrous relationships in search of the perfect woman. One of them is his real life. Another is not his life. And a third is the life he'd like to lead. Which is his true life ?
