CJ7

CJ7

Chow Ti is a poor construction worker. He lives in a partially demolished house with his nine-year-old son, Dicky. Chow is eager to save money so he can continue sending his son to private school. However, Dicky is often bullied by other children and his teacher at school. 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 by. 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. Hesitant at first, Dicky agrees to keep it. The following evening, the green orb transforms into a cuddly alien creature that befriends Dicky. After playing with the alien, he names the alien "CJ7", and then falls asleep. He dreams that the alien will help him gain popularity and good grades at school.

The next day a group of students see the alien with Dicky. They forcibly take it and try to cut it, but nothing seems to work. At last they try to use a driller when Dicky jumps at him. Dicky tries to fight but a fat boy stops him who is stopped by Maggie, a fatter girl. They are then punished for fighting, in which they meet the alien and make a deal of not telling anyone about it. At the construction site Ti shows everyone Dicky's test paper in which he scored a 100. His boss tells him that Dicky changed the marks and is a cheater, on which they fight and Ti gets fired. Ti meets Dicky at home and gets angry at him for lying. He takes the alien, promising to free him if Dicky scores more than 60.

The next day Ti comes to Dicky's school to give him his lunchbox. There he meets Ms. Yuen, who offers to help Dicky study. Ti goes back to his boss and apologizes, his boss does the same and gives him back the job. At work an incident happens and Ti dies. Ms. Yuen tells Dicky about it just when he gets his test result in which he scores 65.

The alien, still in the backpack which is now under the bed on which Ti's dead body is lying, gets out of the backpack and uses his repairing power on the body, even though he knows it will take his full power and he will die. The next morning Dicky finds Ti sleeping next to him. The alien comes out of the backpack, and lies on the table, powerless. The ball inside his antenna falls and burns up, and it turns into a doll.

They try many ways to get him back but end up unsuccessful. In the end, it is shown that everything is back to normal. The fat boy is in love with Maggie who is in love with Dicky who is in love with the other girl who the bully boy takes away. Ti is in love with Ms. Yuen but is "not funny enough" for her. Dicky wears the alien doll as a neck pendant all the time expecting it to come back to life. In the end Dicky sees a UFO landing and many other alien dogs like CJ7 of different colours and patterns come out.
