As a bodyguard at the BKA, Helen Schilling is responsible for the security of the controversial Minister of Economics and Environment Richard Bauer at a press event. When Bauer has a seizure in front of the journalists, it quickly becomes clear: the minister has been the victim of a targeted attack. In the course of the investigation, Helen becomes involved in a highly explosive plot, behind which a war for the dominance of future genetic research and its ethical limits is unfolding. Helen is also under pressure in her private life: like her younger sister Paula, she suffers from a genetically inheritable, fatal disease. In order to fulfill her long-held wish of having a healthy child, she decides to undergo illegal germline therapy abroad. The offer came surprisingly from Dr. Wöllner, the international luminary in the field of gene optimization. Shortly afterwards, events come to a head. Who is using Helen as a pawn in a sophisticated plan?
