In the opening scene, an old man who have a box is entering a house. Suddenly, a window opens and he takes the place of a little boy. A caption tells the stage is "Germany, 1943". I can know this is the story about World War II. There are some traces of someone's life in the house, but no one is there. When the boy goes behind a wall, he finds a girl who has a scared look on her face. She has a yellow star mark on her arm. I know what the meaning of this is because I have read "The Diary of Anne Frank". The yellow badge shows Jewish people. Then, I understand the caption that is "Germany, 1943". The Jewish girl gives him a porcelain unicorn. I don't know a unicorn's reason of existence for Jewish people, but it looks very important. However, suddenly some Nazis break into the house and he and she are in danger. Can the German boy and the Jewish girl make a friendship? I think this movie is sad, but profound and beautiful. I like the connection between the old man at the beginning and the little boy. I also like the expression without useless dialog.
