Grandma has decided to enter her French bulldog Mati into a dog show. To keep the animal and herself from getting too nervous, she invites along her granddaughter Mari, who brings her friends Reilika and Sadu in turn. When Mati finishes with a silver medal, they decide to go say goodbye to the female bulldogs waiting their turn. Alas, their owner Kertu discovers that one is missing: Anna. Kertu hopes to find the dog quickly, as there’s a tracking device on her collar. But when it’s found around the neck of a cat outside the exhibition center, the owner has no choice but to call the police. The girls are certain that the police won’t get to the bottom of it, so they tell Olav and Anton about what happened. Together, the Souptown Secret Society sets out to solve its twelfth case.
