Guigo is in love with Sabrina, with whom he exchanges messages through his cell phone. He is the son of separated parents. One day he and his friend Túlio travel to a fishery with their father, Roberto, and his friend, Paulo.

Four friends are tired of surviving by pulling small scams and running from the police. After a swindle that goes wrong, the quartet formed by Zoinhu, Linguinha, Mãodelo and Alãodelom comes across a robbery that could take them off the streets.

Diogo and Emília have been together for 16 years. They have a teenage daughter and undergo a tedious phase. However, everything turns upside down when they find out their best friends, Ricardo and Bettina, have an open marriage. More than that: they are swingers, are super cool about this choice, and try to convince the other couple that it is possible to be quite happy with this liberal lifestyle. This news comes like a bolt from the blue. After reacting badly to the idea, Emília gets excited and convinces Diogo to, at least, go to a party with Ricardo and Betina's "gang". And that is when a series of events that will shake the couple's boring little life starts. Will they set their jealousy aside and become supporters of this practice?
