YP1967 is a 72 minutes documentary directed by award-winning documentary filmmaker Can To, written by Jenny Lee, and wholly owned by 3a Motion Pictures Limited, an independent Hong Kong film company. Based on meticulous research conducted over many years, official British Colonial Office records only very recently disclosed to the public by operation of archive laws, and highly personal interviews with former young prisoners who have faced the consequences of participating in this truly controversial and little-known social movement over the course of their lifetimes; our film has already touched and enlightened a very select global audience.
