More than three million Vietnamese people still suffer the gruelling effects of chemical weapons used by the United States during the Vietnam War. American militaries doused forests, lands and waterways of Vietnam with the deadly chemicals Agent Orange, White, Blue, Pink, Green and Purple. Agent Orange in particular, which contains dioxin—the most toxic chemical ever known—has disabled countless people and generations of their offspring. This film weaves personal stories together with the stories of American GIs to lead to a great unravelling of the first-hand devastating and lethal effects of Agent Orange and war, generations later.
