Senior high school student Lin Xiaotian is passionate about drone research and development, but is constantly pressured and negated by his parents who practice strict bitter education. With competition prize money, he builds an AI avatar, Daijuan Number One. After taking over the body, the AI subjects the parents to test-taking pressure in the same high-pressure way, and also helps him deal with campus bullying and fight against enterprises coveting the technology. The parents gradually reflect on their education methods, and the family unties their estrangement, joining forces to resist external crises. Lin Xiaotian wins the top scorer in the national college entrance examination and chooses to devote himself to aviation scientific research. As the AI completes its mission and is about to be formatted, he modifies its algorithm and donates it unconditionally to assist family education psychological counseling, starting a new equal and warm life for the family.
