Three relatives of missing people travel a long and complex path in search of the remains of their loved ones, facing bureaucratic, legal and social processes that have persisted since the Civil War. Atlas of disappearance reconstructs what oblivion and repression tried to hide. Through digital maps, archives and forensic architecture, the film illuminates the silent transfer of thousands of missing people to the Cuelgamuros Valley during the Franco dictatorship. Between absences and silences, the film shows the constant struggle to recover the truth, giving name and place to those who were torn from history.
