Plot

The film centers on Andrew, a thirteen-year-old boy stricken with grief over the recent death of his mother. On the day of her death, her radio stops working, and Andrew believes that if he can repair it his mother will return. He is left with a cold, emotionally distant stepfather. He is also teased relentlessly in school, which leads him to bring a gun with him. During an altercation with another student in a physical education class, he fires the gun, injuring no one. Following the incident he receives counseling, is administered a Rorschach inkblot test and is encouraged to open up emotionally. However, his stepfather becomes increasingly brutal. Andrew commits a virtual murder by destroying a photograph of his stepfather, whom he blames for his mother's death; afraid his feelings will lead him to actual homicide, he runs away. By film's end he has recovered, and is adopted by his aunt and her husband.
