First phase

2001 – The story revolves around a wealthy family's struggles for control of the renowned San Magno Hospital, in São Paulo. The hospital belongs to the Khoury family, headed by general practitioner César Khoury (Antonio Fagundes). Most of the family are doctors: Caesar's wife, Pilar (Susana Vieira), is a retired dermatologist and Paloma (Paolla Oliveira), the couple's youngest daughter, has just been accepted to a college to study medicine after several unsuccessful attempts in other areas. Only Felix (Mateus Solano), the eldest son, shows no motivation to follow the same career, but he does not lack ambition. Since he could not be a doctor, Felix studied administration so he could work on the hospital board and plans to one day head the family business. Felix is gay, but married a stylist, Edith (Bárbara Paz), to keep up appearances.

To commemorate Paloma's acceptance into college, the family travels to Machu Picchu in Peru, where Paloma meets Ninho (Juliano Cazarré). Ninho is a backpacker who adopts a lifestyle free of rules and Paloma falls in love with him. Tired of fighting with her mother, she decides to leave the family and college to live with Ninho. The couple spends about a year hitchhiking aimlessly around South America, living in intense passion, until Paloma discovers she is pregnant. Without money and thinking about the baby's future, she decides to return to her parents' home in São Paulo, and convinces Ninho to go with her.

To pay for the ticket, Ninho decides to smuggle drugs during the trip. However, Ninho is detained at the airport in Bolivia after being found with drugs on his body. Paloma flies back to São Paulo alone and trusts her brother to help her face their family. Felix convinces his sister that it would be better to keep her pregnancy a secret. Back in her parents' house, Felix's wife, Edith, helps Paloma disguise her pregnancy by wearing baggy clothes to avoid raising suspicion. Near the end of Paloma's pregnancy, Ninho leaves prison and goes to São Paulo. Felix pretends to help the couple, but really he plans to get rid of them and become the sole heir of the family. Paloma decides to leave home to be with Ninho, but is caught by her parents who are shocked to realize that she is expecting a baby. After arguing with her mother, Paloma leaves and spends the night in a bar with Ninho. After a lot of drinking to celebrate his release from jail, Ninho has a nasty argument with Paloma and says he does not want to start a family. Very disappointed, Paloma sends him away. In her state of anxiety Paloma goes into premature labor, and ends up giving birth to a girl in the bathroom of the bar with the help of bar patron Marcia (Elizabeth Savalla), a former "chacrete" (TV dancer). Felix, who had gone in search of his sister, arrives at the bar to find Paloma unconscious in the bathroom with no one but her newborn daughter at her side. Marcia had called an ambulance and left for fear of being arrested.

Feeling threatened by the infant heir of the Khoury family, Felix kidnaps the child and leaves her in a dumpster in an alley. When she awakes, Paloma cannot find the baby and is convinced that her daughter was mysteriously stolen without a trace. Paloma's path will soon intersect with Bruno (Malvino Salvador), a kind man who just lost his wife and his newborn son due to complications in childbirth. While distressed by that incident, and wandering the streets, Bruno finds Paloma's daughter in a dumpster after he hears her crying. Bruno sees the incident as a divine sign, a chance for him to start a new life, and takes the baby girl home. Bruno receives help from his mother, a nurse named Ordália (Eliane Giardini), who works at the San Magno hospital, as well as an ob/gyn named Glauce (Leona Cavalli). Glauce helps Bruno keep the baby without having to go through the formal adoption process. He asks Glauce to change the hospital record to report that his wife gave birth to two children: a boy, who died, and a surviving girl. In love with Bruno, Glauce does what he asks, risking her career. A pact is made between Bruno, Ordália, and Glauce that this secret will never be revealed.

What Paloma does not realize is that her missing daughter is one of her most beloved patients: Paula (Klara Castanho), a very sweet and smart girl. Paloma has always had a very strong and affectionate bond with Paula, regardless of the fact that Paula is actually Paloma's daughter, and her closeness to Paula forces her to cross paths with Bruno, Paula's father. Paloma and Bruno, who had met years earlier when Paloma had admitted and nursed Paulinha unaware that she was really her daughter. The two separate, but before they realize, they are living together again. Paulinha especially approves of the relationship because she loves Paloma.

United by fate, Bruno, Paloma and Paula are happy until Ninho returns to Brazil determined to regain his relationship with Paloma. Fate holds moments of joy and sadness, revelations and dilemmas. At one point, Paula suffers a serious illness and blood tests reveal that Paloma is the only one who can donate an organ, due to the extremely close similarity of their blood. Suspicious, Paloma secretly orders a DNA test and discovers that Paula is her daughter. She becomes convinced that Bruno stole her daughter twelve years earlier, and their once-close relationship turns to hate. With Ninho, Paloma decides to take Bruno to court to regain custody of Paula. What Paloma cannot imagine is that the real culprit for all this is her brother, Felix, who now, in addition to Paloma, has another an obstacle in his path: Paulinha. Felix is aided by Glauce, who previously in love with Bruno, is happy to hurt Paloma in any way possible. Bruno hires lawyer Silvia (Carol Castro) to defend him.

In addition, the marriage of Cesar and Pilar is threatened by the arrival of the new medical secretary, Aline (Vanessa Giacomo), a beautiful young woman with a mysterious past who will do anything to seduce the head of the hospital and gain revenge on César, who she believes is responsible for the tragedies in her young life.
