The background of the story is Garfield High School in Los Angeles, which is dominated by the children of South American immigrants. Eastland, who used to work for a computer company, came to the school to teach because he was short of money and did not have a computer, so he had to teach math instead. With a strong teaching method, he tamed the stubborn students led by Philip and helped them pass the leapfrog exam with high marks, only to be suspected of collective cheating. In order to clear up the misunderstanding, the students decided to retake the exam, and there was close cooperation between teachers and students, which finally set a record for the number of qualified students, and also won funds for the school to buy and sell computers.
