On ZDF this Wednesday, 7 May 2014 at 7.25 pm, a skull turns up in a fishing net!
The coastguard receives a curious report: in the Baltic Sea, alongside its regular catch, a cutter has hauled a human skull from its nets. It soon emerges that the skull belongs to Sandra Keller, a young woman supposedly travelling the world for the past five years. Shortly afterwards, divers find a lower-leg bone with the same DNA, weighed down by a heavy object. It seems likely that this body was deliberately sunk in the Baltic. Mathias plays the fish trader, who also happens to be the local mayor.
