The blind Yip Man-chiu was abandoned at birth. Following the death of his foster parents, the boy is sold by his uncle Ah Sam to a blind Taoist priest, an abusive man. Running away from home, Yip is hit by a car and sent to a school for the blind by the social security workers. His talents impress the musician Siu Kwong and wins him a place in a music school for the blind. There he is joined by fellow students Lung Kwok-kei, a runaway child with an abusive stepmother, Chow Kuen, an abandoned child found on a train, and Cheung Kin-ching, an avid music lover sent to the school by her loving well-to-do father. The four children blossom into accomplished musicians under the tutelage of Siu and his wife and together with the less fortunate others, form an orchestra which earns a reputation for excellence.

A Shaw Brothers drama starring Diana Chang Chung-Wen and Margaret Tu Chuan.

In 1966, Connie Chan Po-chu and Josephine Siao Fong-fong starred in multiple contemporary films, cementing their onscreen persona as virtuous young women while becoming the hottest youth idols of their time. 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.
