Not sure if I got the spelling right... anyway its also known as Child's Play.
The story is of Micha, a rebellious boy of about 12 or so in Germany around the 1960s. Much like 400Blows and Joe the King, Micha is a rather neglected kid...he feels unwanted and unloved. His mother has just moved out of the house and chooses to bring along his younger brother while he is left to the care of his sometimes violent father.
Micha struggles to prevent the divorce and becomes the mediator between his parents by passing along letters that he sometimes fabricated himself.Of course his naive attempts at bringing his family back together is unsuccessful.
His father angered at being made a fool by Micha, with the letters, started smacking him around. In self defence Micha grabed the nearest thing which was a hammer, struck his father on the head, and his father dies almost instantly.He cries and tries to wake him up. Next we see Micha in the bathtub trying wash his guilt away. And before the credits roll they showed a scene of several police cars in front of the family home. Several things could have happen here. The father does not make an appearance at work and his colleagues alerted the police. They find him dead...and Micha gets into a whole lot of trouble. But I think this seems more likely...Micha kills himself in the bathtub...he feels guilty of his father's death and the fact his family won't be together again. He doesn't visit his mother and so the police goes and check the house. Anyway thats just what I think.
Overall the story is ok...rather sad. Slow at times but still managed to keep me watching.
