España, en 2030, vive bajo una democracia iliberal que aplica el Crédito Social. Todos los ciudadanos están vigilados. Excepto un grupo de subterráneos, que luchan desde su posición marginal. Vega es una de ellos, y tras diez años de distancia ha vuelto a contactar con Virginia, su primera pareja. El motivo: esta trabaja en una farmacéutica y Vega necesita una medicina para su hija.

A fiction film… The country is celebrating the tenth anniversary of its Constitution with a televised gala, which will feature television celebrities and the Prime Minister, a political demagogue who controls the lives of citizens' thanks to Internet and Social Credit. The latter grants points depending on behavior. Vega and Mauro are a couple who live on the fringes of society and fight against the system with the few weapons they have. They have a diabetic daughter and are forced to ask for help from Virginia, a former girlfriend of Vega's, who works for a drug company.
