The camp director of the summer camp paid special attention to the personal safety of the children, so he laid down strict rules and believed that if the rules were broken, accidents would happen. One of the children who attended the summer camp, Inoshkin, broke the rules and was expelled from the camp by the director. But he was afraid that his grandmother, who lived with him, would be sad. Instead of going home, he climbed over the wall and went back to the camp and hid in the cabin in the middle of the square. The next morning, friends found him and quietly helped him, wrestling with adults so that he could stay. Yelim Klimov's debut film, filmed at a real avant-garde camp, discusses the profound motif about children's education in a relaxed and humorous comedy cloak, and is full of childlike and childish narrative perspectives. it makes the theme expression of the film more able to arouse the reflection of the audience.
