In the Pankow apartment house, the grandparents, the mother and her daughters all get together; the government threaten to stop the rehearsals at the Friedrichtstadt-Palast; Marlene moves to West Berlin to live near her mother and sister.
Christine and Marlene get into a fight; the mood in the GDR begins to change and people are calling for reforms; the GDR authorities learn that the twins have repeatedly exchanged passports and identities.
