One year after the earthquake that devastated Abruzzo, Sangue e Cemento retraces recent causes and remote responsibilities of those who built poorly to save on materials and techniques, of those who had to control but did not, of the administrators who favored speculation at the expense of the safety of citizens, who paid a price of 299 victims. Interviews and testimonies to seismologists, geologists, territorial and construction technicians, lawyers and judges enrich this film-document that was made by Gruppo Zero, a collective of journalists, filmmakers and communicators who produce investigative documentaries for correct information and free from manipulation.
