After a celebrated appearance, a star tenor receives a visit from the State Criminal Police Office in the artist's wardrobe. A completely frightened underage boy is found there. The singer is then arrested. But shots are fired in front of the opera that immediately kill the tenor. Singer Lorenz Ammersfeld apparently had contacts in the red light milieu and was silenced by the person who led him to the boy. Research by Laim leads to an initial reception facility for unaccompanied refugee children and the security guard company on site. Then a second body is found.
