The director Nacho Ruiz-Capillas undertakes the digitalisation of over 6,000 photographic negatives, inherited from his grandfather Mariano, a cameraman and graphic reporter from before the Spanish Civil War until the 1960s. While he rescues these from their inevitable chemical fate, his mother Isabel, 88, begins to show signs of dementia, mixing past and present. These two processes of decomposition (that of the celluloid and the human memory) establish an unsettling parallelism that structures the documentary.

Of the World, I'm the Treasure, is a story of resilience set in Potosí, Bolivia, a forgotten world in the depths of the Andes. This documentary portrays a community surviving where life seems improbable, following the lives of nine individuals, men, women, and children, as they navigate a hostile universe defined by labor, poverty, love, and death. Through a blend of raw realism and visual poetry, the film explores the daily struggle for survival: from miners handling dynamite and "pailliri" women crushing rocks, to children selling goods in the streets. It is a profound immersion into the human spirit, capturing the strength, fragility, and shared dream of a better life while honoring the dignity of those hidden behind the statistics of the mining industry.
