In Rio de Janeiro, photographer Ana and writer Carlos are a young couple in crisis. Anna requests more attention and love, but Carlos is trying to concentrate on writing a book. They live in the fancy zone of Lagoa, one of the most expensive places in Rio de Janeiro, in an apartment that belongs to Carlos' mother Yara. On the other side of the same street, former model Andréa and her mate, the publisher Miguel are also in crisis, for similar reasons, since Andréa needs more attention from Miguel. Ana and Carlos receive a surprise visitor, Tomás, who was Ana's former love, and Andréa and Miguel lodge zoologist Cláudia, Miguel's first love, who was living in the USA. The six characters are related in many situations of sex, love, and betrayal (in the sense of affair).
