Superintendent Lascano is a detective working under the shadow of military rule in Buenos Aires in the late 1970s. He is sent to investigate the discovery of two bodies but when he arrives at the roadside crime scene he finds three. Two are clearly the work of the junta's death squads, and so should not be investigated by the police, but the other one seems different. Lascano follows the trail, leading the reader on a tour of a Buenos Aires poisoned to the core by the military regime.
