Nam Yan Sei Sap plot
Lam (Jacky Cheung), a high school Chinese literature teacher, has been watched over for some time by his student Wu (Karena Lam). It becomes clear that Wu wants something more than the weekly interesting classes, but she keeps her feelings in check. At the same time, an argument breaks out between Lam and his wife Ching (Anita Mui) at home because Ching wants to take care of her former teacher (Tou Chung Wah) who has cancer in the hospital. Lam is angry, the reason why remains a mystery for now. It turns out that this former teacher is an acquaintance of Lam.
