Eifel landlady Antonia "Toni" Janssen and Rufus van Berg want to get married without fanfare and in a small circle. Unfortunately for the bride, her mother Heidi has completely different ideas for her only daughter's wedding. She would like to invite the whole village! Rufus doesn't have very good plans either: Toni's no-good "ex" Hajü, who imposes himself as his "best friend" and best man, wants to organize a proper stag party for him. But what the former star chef fears most is a visit from his parents Carl and Luise, whose marriage is in a permanent state of crisis. In fact, Rufus' mother's bad temper exceeds even the worst expectations: Not only is she completely miffed by her husband's constant flirtations, she is also less than enthusiastic about her son's new life. Luise bluntly lets Toni know.
