The story tells the story of a 10-year-old boy who ran away from home due to lack of family care, and then constantly transferred to the family adoption of orphans. In a working-class family, when he found that his mischievous rebellion had annoyed them and planned to abandon him, he even showed his anger by strangling their cat. In the end, he was adopted by an elderly and friendly old woman, whose kindness and patience made him behave. But in a mischief, he was arrested by the police.
