At the end of the 19th century, a young Spanish woman named Trinidad (Gabriela Andrada) arrives in the Wild West together with her mother (Paz Vega) and her sister (Sofía Allepuz), fleeing the justice system that pursues her back home. Defying the roles imposed on women by the society of the time, Trinidad discovers her innate skill with weapons—a talent that allows her to support her family, but also makes her a target of prejudice and enemies, among them the widow Bronson (Karla Sofía Gascón). When the young gunslinger is falsely accused of a crime she didn’t commit, she is forced to become a fugitive, leading a gang of outlaws that will help planning her revenge.
