In Peiting, Hollywood has erupted, and the market town is divided: some see themselves as new stars, while others rant against the thin film and the silly Bavarian clichés. Then Leo Lang is found strangled, a member of the fraternity and a fervent admirer of the film crew. He was supposed to guard the filmmakers' equipment - even the expensive cameras are missing. Was it really a robbery gone wrong? Commissioner Gerhard Weinzirl must delve deep into a secret tunnel in the Ammertal, into the old times of the miners in the Peitinger mine, and into the murky depths of fatal affairs in the seemingly harmless pre-Alpine market town. Along for the ride are the cool Evi, the hot-tempered Jo, and the former colleague Baier, now in retirement.
