Total Blackout: Upon waking up, Commissioner Thiel cannot for the life of him explain how he ended up in this hotel room. And what are Professor Boerne and that giant plush koala doing sitting on the edge of his bed? But things are about to get even worse: A body has been found in the woods nearby. The victim turns out to be Thiel’s former boss from his days with the Hamburg Homicide Squad—a man he hasn't seen in years. Or has he? Professor Boerne is fascinated by Thiel’s amnesia and joins him in the search for clues. (Text: ARD)
