Die seltsamen Methoden des Franz Josef Wanninger

Detective Inspector Franz Josef Wanninger (Beppo Brem), who has been appointed Inspector z.b.V. - for special use - because of his intervertebral disc problems, is always called in when his colleague, the ambitious and somewhat stiff Detective Chief Inspector Wilhelm Steiner (Wolf Ackva) does not really make any progress with his investigations. With the help of assistant detective Toni Fröschl (Maxl Graf), Wanninger investigates in Steiner's eyes with somewhat 'strange methods' when he dives undercover into the milieu. But to the delight of her boss, Detective Director Mitterer (Fritz Strassner), every case, no matter how unsolvable, is solved.
