Grandchild fraudsters scare their victims on the phone with so-called "shock calls". The losses run into millions. Month after month. Many victims are left severely traumatized. But the scam has a weak point. And the izzy team has found it. During a year-long investigation, izzy figurehead Cedric Schild pretends to be an elderly person and supposed victim on the phone. This not only makes for a few laughs, but also drives the perpetrators crazy - at the same time, the editorial team penetrates deep into the structures of the criminal clans. Thanks to more than 1200 minutes of recorded conversations from real shock calls, the izzy film "Die Enkeltrick Betrüger" shows all the tricks used by fraudsters for the first time and thus makes an important contribution to prevention. In cooperation with the law enforcement authorities, the perpetrators are arrested in front of the cameras.
