In Mexico, 61,000 people have gone missing, with no response from the government authorities. Worse still, the State itself is usually directly involved. 65 citizens' collectives have been set up throughout the country, formed mainly by mothers who have to face intimidation and violence in order to pursue the search for their loved ones. This powerful short film, produced by actor Diego Luna, tells the story of a human and humanitarian tragedy, but also the importance of collective action and solidarity to achieve justice.
