Summary A fire in a psychiatric clinic provokes a collapse in the services of the Central and reveals a dark plot against the patients. Among the men injured in the fire is Marcos, an inmate of the clinic, who affirms that the patients are being poisoned. The clinic director roundly denies this, but Javier distrusts her because she seems to be hiding something. Meanwhile, Alonso, who received a mitral valve without complications, returns with more heart problems. Aimé believes that the motive might be the pollution of the operating rooms, which would put to the hospital in a very delicate situation. In addition, Héctor warns that his daughter Daniela is losing her hearing because of the meningitis, but he hesitates to operate on her, fearing that the operation will go wrong. Maca and Dávila advise him to take a decision of immediate form or it will be too late to help her. To the hospital comes Jesús, a 60-year-old seropositive man. The analysis indicate that he might have suffered a poisoning for an inappropriate dose of some medicine. His wife is the one in charge of giving him his medicine, so she becomes a suspect. Vilches is at the expense of Jesús' case and he will try to discover the truth on the circumstances of his disease. Rusti asks Vilches for help after being ruined on the stock market. Aimé receives a job offer in Bruxels.
