When he was a child, Vicente, son of Northeastern migrants, lives in SÃ£o Pauloâ€™s Zona Norte and witnesses an event that will mark his life forever: the tragic death of his mother, victim to the lack of medical assistance. Still in his arms, he makes her a promise: to become a professional doctor. â€œYou make me proud, Vicente,â€ says the mother, just before dying. Vicente grows up dedicated, studying obsessively, revealing a great talent for medicine. Without financial support to attend a respected college, he concludes his studies in an obscure college. In spite of that, his great talent grants him a job as a resident doctor in a private hospital. There he starts to be segregated due to his social origins and witnesses for the first time, the excellent conditions the upper class has while undergoing treatment. Refusing to accept the awful conditions of public health services, he makes a radical decision: to set up a clandestine practice in his own house, where he starts treating the destitute and the marginalized, with the few resources he can gather, undercover, from the hospital. Then, he starts living between two opposing worlds: in one, he tries everything to be promoted and have his talent acknowledged in the hospital; in the other, he clandestinely sees the unassisted in his improvised practice. He wants to seek the cure for a sick world and he also wants to fulfill the promise made to his mother of becoming a respected doctor (the cure to his own dramas and dreams).
However, if he is promoted in the hospital, heâ€™ll need to shut down his practice. And if they find out about the practice, he loses his job in the hospital. Which of these paths will Vicente choose?
