In her youth, Anna made her mark in the lawless wilderness of the West, subduing numerous gangs and establishing ironclad rules: firearms and human exploitation were strictly prohibited within her territory. The underworld dubbed her “The Queen.” She founded Anna Machinery, but her daughter Sophie secretly misappropriated the factory’s machine tools to manufacture guns for cross-border arms smuggling—a scheme that eventually came to light. Deceived by her husband Pete, her daughter Sophie, and her trusted secretary Karen, she was sent to a maximum-security prison on a remote island. Pete bribed various factions within the prison, intending to have her die behind bars so he could seize all her assets. Upon her arrival at the prison, Anna faces a life-or-death crisis. While building her strength behind bars to prepare for revenge, she also fights against the illegal arms trade.
