Juri suspects that his current girlfriend Sybille may have once betrayed him and his former girlfriend Katharina to the Ministry for State Security. Katharina is given an old Stasi file in which an IM "Gänseblümchen" is mentioned - Gänseblümchen is also Sybille's nickname and Katharina and Juri were once betrayed to the State Security before Juri's escape from the GDR because of a song critical of the system. Juri continues to have problems with his dementia-stricken father, who this time runs away from home and gets lost in the Thuringian Forest, where Juri and Katharina search for him and become closer.
Driven by the thought of being the father of Paul, the eldest son of his childhood friend Katharina, Juri Hoffmann stays in his hometown Eisenach instead of returning to his adopted country Canada. In fact, it turns out that Juri is Paul's father and Paul, who has just opened his own medical practice in Eisenach, reacts very disturbed to this information. Juri continues to have problems with his dementia-stricken father, who barricades himself in his house because he imagines the danger of an "imperialist invasion".
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.
