The criminal psychologist Annett Schuster and the case analyst Jan Kawig have to solve their first case together when a male body is found near the Wartburg. Huddled in a fridge like the victim is praying. The man was known as the "Judge Merciless" at the Higher Regional Court of Erfurt - revenge as a motive is therefore obvious. Annett Schuster finds religious symbols that refer to the Bible quote "An eye for an eye".
