Ein Kommissar kehrt zurück (2016)

Sinopsis

Newly retired Chief Inspector Kovak returns to a small village near Greifswald, where a gruesome crime took place 20 years ago. He was unable to solve the case back then because the evidence against the renowned physics professor Adam was not enough. Now he sticks to Adam again and tries to trick him into making a mistake. But the highly intelligent Adam is far superior to Kovak. How far will Kovak go to convict Adam? Is Adam even the culprit or is Kovak just deluded?
