[Banner] Yes, Sir. Sorry, Sir! [点解阿Sir系阿Sir] - Episode 1

The drama serial starts off with a police operation. Lo Sir, who was in the surrounding area, spotted a student buying illegal cigarettes and helped the police capture him. It turns out that Lo "Sir" is called as such not because he's a policeman but a teacher!


The school Lo Sir teaches in, Lam Tin Gwong [林天光], is infamous for having students who are the hardest to handle and is thus described as "Band 3 中的 Band 3".


A misunderstanding with Lo Sir results in K4 wanting revenge. This forced Lo Sir to resign. At the same time, his mum passed away after a long illness. He is down in the dumps.


Lo Sir then decides to apply for the police force, which he has aspired to join since young, partly because his mum's last wish was for him to chase his dreams. Will he be recuited?
