Eight children between four and eleven years old move into a new housing development. They go to the same school and play together. There's the boy Petja and his friends Vincent, Laurin and Maus, and the girl Tara and her friends Tieneke, Fritzi and Jul. They often have different opinions and it doesn't always turn out to be fun. But Möwenweg is ultimately always the most beautiful place in the world.
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.
Pig lives at the top of a hill in a town surrounded by a destructive, dark cloud. Before Pig's father leaves to find a solution to the cloud, he builds Pig a small wooden dam to protect him and the town. The dam's windmill keeps the cloud at bay, and Pig now has the responsibility to care for the dam. Young and alone, Pig finds love and family through his friendship with Fox, and continues to care for the townsfolk in a variety of ways. However, Pig struggles with the absence of his father, and his desire to search for his father competes with his need to keep the town safe.
