Rich businessman Rüdiger Hillmann asks Matula to do a security service during his birthday party, in order to avoid his angry son Alexander to rush there and make a scene. Indeed when this happens, Matula manages to bring him out and to watch him at home until the party's end. But the day after, Hillmann is killed in an explosion and Alexander, obviously the main suspect, asks Matula for help to show his innocence.
