Kyra, 28, is released from Cologne-Ossendorf Prison after ten years. She wants to start over. But she can't. There is a rage bubbling up inside her that she can hardly suppress. She simply cannot understand how she could have been sentenced back then.

As she begins to investigate the events of ten years ago, she discovers that a complex conspiracy seems to be behind it. Her rage breaks out and she does what she was wrongly convicted of years ago: She commits murder.

Killing feels good. Really good. So good, in fact, that she murders her way from the corrupt prosecutor's office to the Cologne underworld with increasing vengeance. So this is what it feels like to have power and control over your own life.

Kyra hides her deeds from her school friend Shannon, whose beauty store Kyra has taken up residence in, and her martial arts training partner and part-time lover, police officer Liam, because regardless of her new criminal lifestyle, Kyra just can't get involved in trusting relationships with other people.

Eventually, Kyra finds that revenge doesn't make her happy, it merely makes her lonely. But now she has penetrated so far into the conspiracy that not only her just regained freedom is at stake, but her very survival.
