HK horror film.

In protecting a group of children from bullying and gang violence, the gallant 'Lady Bond' Kong Yin stays with the family of driver Lee Pak in order to give classes in self-defence to Pak's younger brother Calf and neighbours Tak, Ah-ling as well as the young woman Sheung, drilling them in the moves and techniques. Startled by her striking resemblance to his kidnapped girlfriend Tong Ching-yee, Tse Tsi-ming pleads with and convinces Kong to pose as the missing girl to visit her bedridden grandfather Chung-sau. The masterminds behind the abduction, Tong's stepmother and her nephew Chan Chi-biu capture also Tse and the children. Tse brilliantly manages to alert Kong. Fighting and apprehending her opponents, Kong frees the hostages and hands the criminals over to the authorities.

A ghost tale very strongly inspired by Hitchcock's Vertigo.

Colourful Youth remains the only contemporary film to feature both of them. Filmed in Eastmancolor, the song-and-dance spectacle keeps its fingers on the pulse of its era and presents the vigour of the modern times.
