Leonardo, an upper-middle class boy from the south of Rio de Janeiro, befriends Kiko, a boy who lives on the street and who juggles balls at a traffic light. The rich kid decides to lend Kiko his handheld video game – but it is stolen by hill boys. This is just the beginning of a great friendship between the two. They begin a great adventure that takes Leonardo to the favela, where he knows a reality entirely different from his own.

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.
