The wedding bells are finally set to ring out, and the whole of Grossraming is eager to find out whether, after several false starts, Dr. Johanna Lohmann (Christine Neubauer) will finally step up to the altar with her fiancé, the vet Laurenz Hofer (Timothy Peach). Johanna’s son Max (Daniel Perez) and his new friend Bastian (Simon Jung) - an orphan who has been adopted by the doctor – are also looking forward to the celebrations. By chance Johanna stumbles upon an indication as to the identity of Bastian’s father: the boy's late mother always refused to name the man. But it now appears that it might be Daniel Winterberg (Sven Martinek), a horse-breather from a neighbouring village. Winterberg denies that he is the father... but demonstrates a great deal of interest in Johanna. And if she is honest, her encounter with him also at prompts feelings in her which are not entirely appropriate for a woman who is about to get married. However, Johanna doesn't have much time to think about all this: Laurenz has found traces of a deadly pesticide in a dying deer.  And one of Johanna’s patience is suffering from inexplicable breathing difficulties. Everything suggests that pesticides have been dumped illegally in a nearby field. And when Bastian disregards all warnings and enters the field, he suffers an allergic shock which is potentially fatal. Will Johanna be able to save the boy? Will Bastian have to continue to grow up without a father? And will Johanna and Laurenz finally say "I do"?
