Following the cold-blooded murder of her niece, committed by the girl's own father, Luisa Salazar attends the trial of the accused, who, due to the lack of concrete evidence, is released. A legal technicality that only highlights the injustice of a society in which the rights of the most vulnerable are violated by business leaders, political classes, and elites who hold power. After a fit of rage, Luisa decides to take justice into her own hands; a fit of rage that leads her to the whereabouts of the accused: Bruno Zapata. Her only weapon is a kitchen knife, and, behind a makeshift outfit consisting of a wig and goggles, she decides to put an end to her miserable life.
The mission turns into a bloody beating that leaves her on the brink of death. It's then that the unexpected appearance of a man in a sophisticated battle suit rescues her, setting in motion a series of training sessions that will lead her to spread terror in the streets, exterminating all manner of corrupt and ruthless individuals in her wake. Alexander Eder, a powerful businessman dedicated to silently fighting injustice, will be a sort of mentor on Luisa Salazar's path and her only bridge to the long-awaited REVENGE.
