The film tells the true story of Carla Antonella Rodríguez, the first female miner in a region of Argentina where women were forbidden to work in the mines. Miss Carbón is a story about overcoming, passion and dreams that do not understand gender, as Carlita managed to become the first female miner in a town where women were forbidden to access the main source of income in the region: the coal mine. For there was a superstition that women could cause a collapse and mining work was reserved exclusively for men. But, as a trans woman, she managed to enter the mine, breaking the system from within and igniting a spark of social revolution.
