Despite the fact that he comes from a long line of disciplined workers, LAW YIU-WAH (Moses Chan) is a teacher of a notorious school. One day, he is urged to resign after being vilified by his students as a peeping Tom. The triad has expanded their drug network at local schools. WAH, who has turned a cop, is told to go undercover at the school where he used to teach. He is impressed by the enthusiasm of a new teacher HO MIU-SUET (Tavia Yeung).

With a view to boosting students’ confidence, SUET invites bowling expert KOO KA-LAM (Linda Chung) to teach bowling at the school. WAH decides to go after LAM when he learns about her triad background. The next thing he knows, he is in a contest of wits with Inspector CHING MAN-LIK (Ron Ng), as he has been assigned to work as a liaison officer at the school. On the other hand, MAN gets attracted to SUET but she only loves WAH. All of a sudden, WAH, SUET, LAM and LIK find themselves involved in a complicated love polygon filled with laughter and tears.
