Dioxin, a compound found in Agent Orange, is recognized as the most toxic man-made chemical. We dumped it on Vietnam and we dumped it on the dusty backroads of Southern Missouri.

Vietnam: The Secret Agent is the first comprehensive look at the history, the effects and the implications of the deadly contaminant 2,4,5-T — a main ingredient of the defoliant code-named Agent Orange during the Vietnam War. Using rare archival and striking war footage in support of interviews with veterans, scientists, attorneys and representatives of the U.S. Air Force, the VA and Dow Chemical — this film documents the history of chemical warfare and the plight of our Vietnam vets.

Every issue raised in the film continues to resonate in today's political climate. As soldiers return from Iraq and Afghanistan, plagued by illness, disability and post-traumatic stress, as Americans — particularly students — question political decisions, it's critical to learn from past conflicts.

This award winning 1984 documentary classic, with original score by Country Joe McDonald, re-released on DVD, is loaded with new bonus interviews: class action update, eye witness accounts from Vietnam, dioxin problem solving, U.S. veterans today, and more.
