In the Hong Kong resettlement area in the 1970s, Tiger, a primary school student who wore a cat mask, fooled around all day during the summer holiday. Tiger’s mother was angry about this. She stopped Tiger from hanging around and told him to do his homework. Tiger started to fight the homework monsters: Chinese, Mathematics and English. Tiger had to defeat them level by level to get his homework done. After a fierce battle, all the homework monsters were finally destroyed by Tiger.
