Michi and Vicky are getting married. And Eder is supposed to be Michi's best man. So far, so good, if it weren't for Pumuckl, who also wants to experience the great feeling of love that Eder raves about. Pumuckl also wants to be swept off his feet, sail into the harbor of marriage, and anchor a three-masted ship directly in the bay of matrimony. And so the wedding celebration turns out very differently than everyone had imagined.
