Ira, 20, a serial killer who was abducted as a child, starts therapy with celebrity therapist Clarissa. Only one of them knows that they share a mutual secret from the past. Will the other one realize it before she gets murdered?

Clarissa is a middle-aged psychotherapist, the best in her field. She is familiar to everyone from her TV appearances and from glossy magazines. For her, every patient is a princess. And someone only she can save. Or can she? Clarissa already has one suicide to answer for; a teenage boy’s death never seizes to haunt her.

When Ira becomes Clarissa’s patient, a cat-and-mouse game begins in which rules are followed by no one. The kind of game that never ends well.
