Ecologist Theo Barner goes missing two days after a forest brawl during which he seized the rifle of hunter Hansjörg Strack, who destroyed his candid game camera. Theo asked his girl friend to contact the the police if he ever went missing, given the hostility of hunters to his cameras. One recorded a masked man attacking Theo Barner, who isn't found. The team looks into Hansjörg Strack and innkeeper Hannes Krusska, his hunting concession partner, who for one lied about calling a taxi after a drunk party.
