Ex-con local adolescent Micha Moser trained his demented grandma's rottweiler for dog fights and terrorizes the school kids. Beig his age, Bertie is pressed by the kids to trap him into revealing the secret location of the illegal arena by pretending he trained the Hansen dog pretzel, a cute pooch, and wants to fight with him. Grumpy farmer Bischek, the vet practice's worst debtor, would rather delay therapy then pay up, but seeing Annette restores an old cuckoo clock, offers another deal: paying in antique kind, unaware his clock was his father's secret hiding lace for valuable old coins, found when the playing brats drop the clock.
