New edition of the prevention magazine show originally hosted by Eduard Zimmermann. Rudi Cerne, the current presenter of "Aktenzeichen XY ...ungelöst", hosts the show on ZDF on Saturday afternoons. Under the motto "Prevention, tips and tricks", Cerne uses specific cases to show how people can protect themselves against fraud, rip-offs and burglary in everyday life. The various scams are re-enacted in short clips. Real victims and prevention experts from the police and the consumer protection sector also have their say. (Text: RD)
