Chow Ti is a poor laborer working on construction sites. He lives in a partially demolished house with his son Dicky. 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 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 better than the robot they saw earlier.
