Introduction:

Chow Ti (Stephen Chow) is a poor laborer working on construction sites. He lives in a partially demolished house with his son, Dicky (Xu Jiao). Chow is eager to save money so he can continue sending his son to private school, to ensure that his life will be better in the future. However, Dicky is often bullied by other children and his teacher (mainly due to his lowly status), and he usually finds comfort with a young teacher, Ms. Yuen.

One day, while at a department store, Dicky begs his father to buy him a popular robotic toy called CJ1. Chow cannot afford it, and the situation ends badly when Chow spanks the stubborn Dicky in front of other customers. Again, Dicky finds comfort in Ms. Yuen, who is passing. That night, Chow visits the junkyard where he often picks up home appliances and clothes for Dicky. He finds a strange green orb and takes it home, telling Dicky that it is a new toy, better than the robot they saw earlier. Dicky is hesitant at first, but agrees to keep it. The following evening, the orb transforms into a cuddly alien creature that befriends Dicky. After playing, he names the alien “CJ7″, and then falls asleep. He dreams that the alien will help him gain popularity and good grades at school. Buoyed by his dream, Dicky takes CJ7 to school the following morning, but he receives a zero on his exam and is humiliated during physical education. Frustrated, Dicky tries to dispose of the CJ7, but realizes his mistake and later reconciles with it. The next day, because of his alien pet, Dicky begins to make new friends at school. However, when his father discovers that he lied about his bad exam result, Chow confiscates CJ7, arguing that Dicky will never pass school if there are distractions. The father and son fall out and, predictably, Dicky sticks close to Ms. Yuen, who promises she will look after him. This cheers Chow up somewhat, who fears he might lose his son’s love.
