The Peppercorns

Jana is forced to babysit her half-brother Janni because Jacqueline wants to write an article for Interieur Exquisite. But Jana is doing her student internship. She can't possibly take Janni with her to the Katharinentafel, a social institution that collects unsold food and distributes it to the needy. As luck would have it, Jana notices a Katharinentafel minibus in the yard of the Petersen butcher's shop. She puts Janni in the back and asks the driver to take her with him. But he just drives off, leaving Janni alone in the back! Jana is desperate. How is she supposed to find Janni again?
