[2][3] It stars Valentino Lanús as Fernando Bonilla, an engineer with a beautiful family, along with Ana Layevska as Estefanía Braun,[4] and Ilse Salas as Bibiana.

Engineer Fernando Bonilla (Valentino Lanús) lives the most intense weekend of his life in the company of Estefanía Braun (Ana Layevska), a woman too beautiful and intelligent to be true.

Fernando is not a man of infidelity or secrecy, but this one sin seems to be behind during the breakfast conversation between them, which makes it clear that what happened is nothing more than an escape from life and that everything has to return to normal.

That afternoon, Fernando lies to Bibiana (Ilse Salas), his wife, for the first time in his life, so he can escape from his house and go to the meeting point indicated in the letter.

At six in the afternoon has arrived at a dark room where suddenly a projector lights and like blades of a guillotine appears in the screen a video that relates in sequence the homicide committed by Fernando the previous night.
