Matryoshka that tells the story of the organization and resistance of the Mothers and Grandmothers of Plaza de Mayo to recover their grandchildren taken by the civil-military dictatorship imposed in Argentina in 1976, which, as part of the political persecution imposed on communist and socialist militants from organizations such as Montoneros and the People's Revolutionary Army (ERP), took their children to be delivered to families close to the authorities of the dictatorship.

The uprooting of these children was an attempt by the dictatorship to cut off the channel of transmission of communist and socialist education to children. The recovery by the Grandmothers of Plaza de Mayo of the 139 grandchildren, each represented in a small matryoshka, is not only a physical recovery but also an ideological recovery of the education that militant parents would have given their children.
