Text taken from the intro
QUOTE
"The story you are about to see is base on true events that took place in North Viet Nam. In 1952-54, unseen by the outside world, Ho Chi Minh's communists imposed a reign of terror through out the countryside to eliminate the opposition. This led to the massive exodus of one million refugees to the republic of South Vietnam. All actors and extras in the film are actual refugees, portraying their own tragic stories."
Watch the movie to learn the truth about HCM government.
