This could be good–the undercover cops are a blond Anthony Wong, posing as a priest, and the usually-entertaining Sam Lee, trying to pass himself off as a teacher. Also in the cast are Gillian Chung (of the musical group Twins), and Rachel Fu Tin Wing (also a singer, formerly known as Skinny Girl), who plays a character with a black belt in karate.
