Apnea presents a week in the life of Chris and her friends. Chris does not want to sleep. Afraid of her sleep apnea and her own unconsciousness, Chris stays up several nights in search of some sort of sense to her life that she did not see during the day, always living on the edge of her own body, and of existence itself, and dragging everything around with her.

The search for a successor provokes the beginning of a clash between two young and talented executives of his group: Daniel Bastos, a lad of simple origins and excellent character, who is not only handsome and charming, but also intelligent and skilled, and Olavo Novaes, an ambitious and unscrupulous man who is ready to fight for the position, at any cost. To fight against Olavo‘s treacherous plans, Daniel will have the help of the sweet and sensitive Paula, a young lady raised as an only child who founds, on the eve of her mother‘s death, that she is adopted and has a family. What Paula does not know is that she has an identical twin sister, the wicked Taís, who is as ambitious and unscrupulous as the man who becomes her main ally, Olavo Novaes. Antenor, for his part, decides on having an heir when he meets the headstrong and honest Lúcia, a woman who will make this cold businessman find true love is and a real reason to live.
