When Detective Sarah Chen's family is brutally murdered, the justice system fails her—the killer walks free on a technicality. Consumed by grief and rage, she abandons her badge and disappears into the city's underworld. Years later, a vigilante known only as "The Avenger" begins eliminating criminals who escaped the law. As the body count rises, her former partner races to unmask the vigilante before her family's killer strikes again. But when Sarah finally corners the murderer, she must choose between the vengeance that has defined her and the person she once was. Some justice costs everything.
