Isabelle Cordova, aka "Dizzy", is 23 years old and she just gets out of prison. During the metro ride that finally takes her home, a man approaches her. He is a man who is a member of the police force Graves. He reminds her of these cruel memories, those of the death of her whole family, shot by a gang. Finally, that's what she believed. Graves announces to her that the real culprits are dirty cops. He then offers her a briefcase that contains a weapon and 100 unidentifiable cartridges. Graves tells her that she will be able to revenge by having a white card. According to him, no representative of the law will be able to reach her and that there will be no investigation if she proceeds.
