This documentary dives into the tireless work of activists from the Memory, Truth, Justice, Reparations, and Democracy collectives (MTJRD) based in Rio de Janeiro. People from all walks of life come together through horizontal, non-hierarchical, and collectively organized practices to fight for the preservation of memory and justice within civil society. Over nearly four decades, their shared labor, rooted in collaboration rather than individual leadership, has laid the groundwork for the creation of a Museum of Human Rights in the now crumbling and shuttered eclectic landmark that once housed Rio’s DOPS, the Departamento de Ordem Política e Social (Department of Political and Social Order). A powerful symbol of state repression under Brazil’s military dictatorship (1964–1985), the abandoned building still holds a wealth of material history, including scores of severely deteriorated documents that have been patiently recovered and archived by the activist collectives.
