The body of a priest candidate is found above the rooftops of Vienna. The dead man is a protégé of the respected seminar leader Wimmer. The first clue leads the blind special investigator Alexander Haller and his companion Niko to the noble palace of the Brohnsteins, who run a popular techno club there. A plan of the cellar vault that the dead man made arouses the interest of the investigators, as does the strange behavior of the Brohnstein brothers: Johannes and Felix want to shield their sister Fanny, a well-known concert cellist, from questioning. Although Commissioner Laura Janda wants to deal with the Brohnsteins discreetly, who have had to deal with serious blows of fate in the past, Niko can hardly be stopped. He believes that the siblings have something to hide. He and Haller also encounter surprises in the seminary. To Regens Wimmer's horror, who the victim really was comes to light, as do inconsistencies in his establishment.—ADR Das Erste
