Day-care centre director Katharina is still attracted to her childhood sweetheart Juri Hoffmann. He spends a night of drinking with his best friend Christian and Katharina's best friend Sybille, which makes Katharina and especially Christian's wife Yvonne jealous. Tensions also arise between Sybille and Katharina, who are also colleagues. Meanwhile, Katharina's husband Georg is jealous of Juri, with whom Katharina almost became intimate if Sybille - who for her part has a strong interest in Juri - had not interrupted her. In a discussion with Georg and Juri, Katharina makes it clear to both of them that she wants to stay together with Georg. Katharina denies Yuri's question whether Katharina's first-born son is his. Juri continues to have problems with his dementia-stricken father, for whom Katharina finds him a carer, so Juri plans his return flight to Canada. Whether he actually takes off remains open at the end of the film.
30 years ago, Juri fled the GDR for the West via the Prague embassy and built up an existence in Canada. Thirty years later, he returns to his hometown of Eisenach to take care of his demented father, a former veterinarian. He also meets his former girlfriend Katharina again, who did not follow him onto the embassy grounds back in Prague and whom he has not seen again since. Katharina has been married for years now and is the mother of a grown-up son and a teenage daughter. She helps Juri find a place for his father in a nursing home and soon feels drawn to Juri again. Juri wants to return to Canada, but since the home placement for his father fails, Juri stays in Eisenach.
For Johannes and Lydia Klare, their faith in God comes first. Together they lead a small community in Stuttgart, successfully. People listen to them, they are becoming more and more close to them. There are even plans to make the donor-funded community much bigger by the generous contributions of Volker. First of all, the couple have quite different, more urgent points to take care of. When one day they watch the homeless street-boy Simon drifting back and forth in drug-related crises, they take him in for a short while. Together they want to help him again on the right path. But it is not just the drugs that are causing conflicts. Simon's homosexuality also presents the two with great challenge, since it is not so easy to unite with their faith.
Once again, the "border crossing" is celebrated, as every seven years in the Upper Hessian town of Bergen. It is really turbulent at this folk festival, when the municipal boundaries are confirmed from old tradition and everything is upside down. For this occasion leaves Thomas Weidmann his girlfriend and flees because of his botched university career from the city of Berlin back to his native village. At the party, he meets Kerstin Werner, whose life has just come out of joint - her marriage is broken and her husband Jürgen on the jump to another, younger woman.
