Pablo Simó's life is a mess. His career as an architect is at a dead-end; reduced to designing soulless office buildings desecrating the heart of Buenos Aires. His marriage seems to be one endless argument with his wife over the theatrics of their rebellious teenage daughter. Everything changes with the unexpected appearance of Leonor, a beautiful young woman living in the apartment of Nelso Jara, a blackmailer murdered and buried in the foundations of a building finished twenty years before.
