After her sister's murder, Norma Mesino takes the helm of the Peasant Organization of the Southern Sierra, a group that for 30 years has been fighting for the human rights of peasants living in one of the poorest and most violent regions of Mexico. She carries the weight of a surname synonymous with struggle and resistance, marked by the Aguas Blancas massacre, imprisonments, assassinations, and disappearances, while in her daily life she continues her almost invisible work to overcome the atmosphere of hostility and impunity that surrounds her, thus fulfilling what seems to be her manifest destiny.
