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.

Five actors meet in a house on Christmas Eve to make a movie. While waiting to have dinner with someone they don't know or if they're actually going to show up, they reveal secrets and look back on their lives. From this encounter, joys, frustrations, absences and passions surface at the edge of tension.

After a shooting assignment, Henrique is mugged by two armed motor-bikers who steal his camera and speed off. Seconds later, he watches both get hit by a pickup truck driven by a self-appointed avenger, someone weary of feeling defenseless against the urban violence, and who decided to take action. Henrique recovers his stolen equipment and leaves, feeling avenged. But he goes back to find the memory card, with the photos, lost during the crash. From that moment, he is trapped in a situation where he is now the criminal for failing to rescue a victim, who had been his aggressor. Going from the murder scene to the police station, and then to the emergency ward of the public hospital, he attempts to clear himself.
