The film is a fascinating insight into post-war life in East Berlin seen through the behaviour (and misbehaviour) of a bunch of normal teenage kids living in shattered remains of the German capital.
The story reflects the 'angst' suffered by all young people at the crossroads of life and their inevitable clash with authority - in this case not only their parents but also the communist Volkspolizei.
As with any film made in the DDR (communist East Germany) it carries a strong message of the need for everyone to cooperate and behave responsibly. The 'peoples' police and youth officials of the Vopo and FDJ are shown as caring and understanding, seeking only to keep youngsters (who are clearly being mislead by adverse Western capitalist influences) on the 'socialist' straight and narrow.
The acting is excellent and the storyline is gripping and believable, despite the political preaching and unavoidable directorial restraint. The action takes place 2 or 3 years before the Berlin Wall was erected (in 1961). The kids can still pass freely into the Western zones, so there are interesting background views of the ruined city and the occupation zones.
If, like me, you are drawn to this world-changing period of history, this film is a 'must see'.
