Watch at FMovies. A film about three teenagers - Klara, Mina and Tanutscha - from the Berlin district of Kreuzberg. The trio have known each other since Kindergarten and have plenty in common. The three 15-year-olds are the best of friends; they are spending the summer at Prinzenbad, a large open-air swimming pool at the heart of the district where they live. They're feeling pretty grown up, and are convinced they've now left their childhood behind.
