The story is loosely based on the first juvenile murder case in Taiwan that happened in 1961. Students joined gangs to have a sense of belonging and the secret police were arresting people who were suspected to be communists.
Liked the nice songs, the detailed depiction of the life in Taiwan back in the early sixties and the theme of finding one's identity and purpose in life! The three sisters of Zhang Zhen all looked quite pretty!
