Baker Katharina Achternhagen and pastry chef Alberto Puccini have been neighbors for almost 20 years. As their ideas about baked goods could not be more different, they have nothing but derision for each other. While Puccini offers real sugar bombs, Achternhagen is only interested in wholemeal products. Both have successful businesses with regular customers for years. The quality of their baked goods also speaks for itself. Puccini wins awards from the bakers' guild year after year and Achternhagen's Kraftmeier bread has also won several awards. Only this year, Achternhagen also won the cake competition with its diet cake. This is mainly due to the fact that the new chairman of the bakers' guild, Günter Zichorius, has secretly fallen in love with Achternhagen.
