In the spring of 1992, I - the film director - met two long-term political prisoners who were charged of political spy from North Korea. They didn't give up their faith to communism for 30 years in jail.

I want to tell a brick wall which I felt while I had met the long-term political prisoners during this work because I think it is inevitable on the way to the unification of North and South to admit and face up the wall. The unification, won't come true just by praying or declaration, and however active the cultural and economical exchange may be, will never be accomplished as long as the wall exists.
