Based on the novel by Daniel Valdés, the screenplay was written with the collaboration from Ricardo GonzálezIglesias and Mónica Pérez Capilla. The film was produced by Plot Films alongside Els Quatre Gats and Cre Acción Films.
Ángel Fernández-Santos of El País deemed the film to be a "lively and undoubtedly risky fiction", "but stylistically it does not live up to that risk and ambition, and it is stammering and imprecise" vis-à-vis the depiction of the "hellish dumps where the human plunderings of drug and juveniledestitution rot in Madrid".
