Summary Grandma Leni finally has the last installment for her new deep fryer together and drives to the bank with Jessi in the sidecar. There it turns out that some of the banknotes are counterfeit. The police confiscate them and Grandma Leni has to fear for her livelihood. The "peppercorns" are convinced that the counterfeits must have come from a rather careless customer and repeat offender. Who is stupid enough to pay several times at the same snack bar with counterfeit 50 euro notes? Anton builds a counterfeit money detector and lies in wait with Niklas. It doesn't take long before they catch a boy their age. The perpetrator escapes, but Niklas recognizes him: he and Robin were in the same children's home a few years ago and were close friends. Anton, Ceyda, Jessi and Luis have no idea of the dilemma Niklas is in: Should he cover for Robin, lie to his "peppercorn" friends and ultimately harm Grandma Leni? He dares to go it alone and confronts his friend. But the case is not so easy to solve. Because behind Robin's criminal activities are a counterfeit money ring and an unscrupulous stepfather.
