Tatort S2008E18 - Ritter - 25 - Blinder Glaube

Katja Manteuffel, chief physician at the Berlin University Eye Clinic, is found murdered. The investigations lead Ritter (Dominic Raacke) and Stark (Boris Aljinovic) to Cornea AG, a company that has developed a revolutionary retina chip as part of the top-secret 'Phydra' project. This chip was implanted in a blind patient (Anne Kanis) shortly after Katja Manteuffel was murdered. Soon the eye surgeon Mareike Andresen (Judith Engel) is targeted by the inspectors. Because of the murder of Katja Manteuffel, she carried out the sensational operation. A unique opportunity for the career of the young doctor.
But did she kill for it? When Ritter and Stark find out that the murdered woman was secretly in love with Tim Nicolai (Justus von Dohnányi), Mareike's fiancéAndresen and director of 'Phydra', he too is under suspicion. Did Katja Manteuffel threaten Tim Nicolai to tell his fiancee about the relationship? It would have meant Nicolai's dismissal from the company, because the CEO of Cornea AG is Mareike's father Manfred Andresen (Jörg Gudzuhn). But that's not all: from the attractive scientific employee Judith Wenger (Gesine Cukrowski), Ritter learns that the Federal Ministry of Education and Research is significantly financing 'Phydra'.
It is becoming increasingly clear that the key to enlightenment lies hidden in the thicket of relationships between research and business, in which profit thinking and tough competition rule. Knight and Stark must unravel a web of lies and end up with an amazing solution.
