"El Rati Horror Show" is a documentary that portrays the dramatic story of Fernando Ariel Carrera, the case of an ordinary man wrongly sentenced to thirty years in prison - not by mistake but deliberately - through the manipulation of a judicial case in Argentina. The film takes as its central point the way in which Fernando Carrera's case was fabricated: the manipulation and alteration of evidence at the scene of the crime; the manipulation of all national media by Rubén Maugeri, key witness to the events and president of the Association of Friends of Commissary 34. On the other hand, it shows how Fernando Carrera leads his daily life in prison.
