Synopsis by Jonathan Crow
Prolific and controversial director Wong Jing spins this crime comedy, clearly inspired by Stephen Chiau's wildly successful Fight Back to School. Nebbish undercover cop Hou Shui-ken (Alfred Cheung Kin-ting) is assigned to pose as a teacher and given the unenviable mission of finding the student with a dog-shaped birthmark on his rear end in order to protect the lad from triad thugs. Hou quickly discovers that the rigors of police work pale in comparison to tending to his boisterous, hormonal charges. To make matters worse, Hou learns that his ex-girlfriend is also working undercover -- as his student. Later, Taiwanese assassins take over the school prom. This film also features Wong regulars such as Chingmy Yau Suk-ching, Aaron Kwok Fu-shing, and Sharla Cheung Man.
