Leipzig in 1989 – Germany divided into East and West. The twelve-year-old friends Fritzi and Sophie don't care much about this - until Sophie has to flee to the West with her mother. There she struggles with prejudices against 'those from over there', but above all with her homesickness. Fritzi's attempt to at least bring Sophie her dog Sputnik fails because of the heavily guarded border. Fritzi realizes that only the fight for freedom in her country can bring the two of them together again.
