For three days, travelling through vacant and desert lands, under the incipient sun, the recording team accompanied the ‘Seeking Mothers of Sonora’ in the north-western region of Mexico on one more of their expeditions. Hundreds of mothers joined forces to act against the inefficiency and indifference of the authorities and to be able to respond to the disappearances of their relatives. The pain has made Paty stronger. Before she was a mother and housewife but now she does not care if in her search the murderers of organised crime kill her. It is a threat with which she, and all the mothers with her, lives every day. Now she has nothing to lose, after her two sons disappearance she has, as she says, already lost everything. At the same time, the collective actions mean an open denunciation of the violence that Mexico experiences every day and that currently mourns more than 100,000 victims. We accompany Paty in her search for missing bodies, next to other women. The disappearance of their relatives made them move from their home, community and even their state. Paty is a searching mother whose hope to find the final destiny of her sons makes her walk into the desert, in a fight for justice and truth that becomes everyone‘s.
