Santiago, 1992 Rodrigo Quintana, Piedad Estévez, Julián García and Benjamín Morandé are inseparable friends. Idealistic in their planning of future projects, they study medicine and dream of working together to help the needy. Rodrigo is the most charming and intelligent, and is the natural leader of the group. His personality wins over Piedad with whom he shares an intense but tumultuous love, while Julián loves Piedad in silence. Rodrigo's drug and alcohol addiction result in the deterioration of his relationship with Piedad. He reaches a point where he disappears from his friends' lives, after a confusing incident that results in a dead body and in Piedad being hospitalized. Rodrigo Quintana leaves his friends and his studies to admit himself into a rehabilitation center outside of Chile. Piedad is never the same again. Santiago, 2007 Now, 15 years later, when Benjamín, Julián, and Piedad have forgotten about the past, Rodrigo returns to their lives. Partners in an ophthalmology practice, the three doctors find that Rodrigo Quintana's return from Europe continues to bother them. The friends have changed. Quintana opts for an austere lifestyle in a rural clinic, while his friends accumulate a small fortune operating on the eyes of high-society people. Rodrigo's return breaks Piedad's daily routine, who discovers that in spite of everything, Rodrigo is still the love of her life. Meanwhile, Julián—divorced for a year from Matilde —becomes preoccupied with Piedad. It bothers Julián that history could repeat itself, and that Rodrigo could finally succeed in taking away the woman Julián's always loved but has never been able to have. But love is not the only thing that changes the lives of this group of friends. While they are all at a benefit event, they are witnesses to a crime. The victim, María Gracia Carpenter, a well-known socialite, is the third murder that torments the city. Before her, the mysterious disappearance of Angela Argento, a sophisticated executive, was very closely followed by the media and the police. They concluded that they were in the presence of a psychopath serial killer, whose victims were beautiful, independent, high-society women. All were killed using the same M.O., a deep and accurate cut to remove their hearts. The lead police detective Eva Zanetti is in charge of the investigation. Everyone is a suspect. Slowly the circle of suspects is tightened, and the suspects are reined in. Only one is the killer, and with the passing of time the hour of the discovery of the killer's true identity draws closer.
