Renowned psychoanalyst Pablo Rouviot returns to his country after twenty years. But his homecoming is marked by unresolved issues from his past, which welcome him in the form of Urioste, the father of a murdered young woman, who harbors resentment toward Pablo, and his own estranged family. When his older brother, José, is found dead, apparently by suicide, Pablo is the only one convinced that it is a murder. With the help of Officer Cecilia Bermúdez, the only one in the police force who believes in his theory, Pablo takes on the investigation, uncovering a much larger scheme with a serial killer at its core.
