Reporter Alex Winter, daughter of the (police) psychiatrist Wendelin Winter wants to write an article about the confessed and convicted serial killer Gerd Granitzka. Digging into the 3 murders for which Granitzka is convicted they soon find several big holes in the burden of proof. They confront the murderer himself, the police psychiatrist, the police officer, who worked on the cases and the DA who sampled the burden of proof and find themselves in a dark web spinning almost out of control. Alex and her friend the police detective Don Becker find more and more proof that Granitzky didn't commit the murders but probably a witness, who as it turns out, testified in all 3 cases. To silence Dr. Winter they have him committed in the same ward as Granitzky and then the ever clever Wendelin Winter can work on Granitzka.
