In a world full of superman, several superman stand out. They always appear in times of crisis to save people from fire and water, but in real life, the couple are acting as real estate agents, and their children are the protagonists of the film.

Da Zhuang found that he didn't inherit his parents' superpowers, which made him embarrassed, but he didn't tell his parents, fearing that their parents couldn't accept this fact. Dazhuang's high school will be spent in Superman College, which specializes in training children with super powers, so that they can master all kinds of skills and become heroes to save mankind. The students here have all kinds of superpowers, such as freezing, being in two places, moving quickly and so on.

When he first arrived at school, Da Zhuang met Xiaomei, the headmaster of a female student who fascinated him. Then he began to divide classes according to everyone's ability. Those who are powerful are classified as heroes, and those who are capable of being dirty can only be classified as followers of heroes.

Of course, Da Zhuang, who has no super power, was assigned to the auxiliary class and became the laughing stock of the hero class, which made him feel ashamed. But with his friends, he can still live at school. Da Zhuang met a fire man, whose father and Da Zhuang's father were classmates, but the fire man's father went astray and was sent to prison by Da Zhuang's father. The fire man was so angry that he even wanted to kill Dazhuang to avenge his father.

At the critical moment, Da Zhuang's potential super power was aroused and he had the super power like his father. As a result, Da Zhuang was transferred to the hero class and slowly moved away from his friends in the auxiliary class. In the hero class, Xiaomei, the principal of Dazhuang and the beautiful students, became deskmates, Dazhuang became stronger and stronger, and stood out as a hero in the school.
