Nearly 60 years following the use of Agent Orange in the Vietnam War, the deadliest use of chemical warfare in history, the devastating aftereffects of the toxin remain lethal, demanding attention both in Vietnam and at home in America. This documentary closely follows two activists as they take on the chemical industry, and demand accountability for the pernicious legacy caused by the use of this poisonous herbicide. French-Vietnamese activist Tran To Nga and American activist Carol Van Strum are joined in mutual pain and purpose in their quest for justice.
