Thirty-two years after the end of the Vietnam War, the victims and their attorneys, scientists and activists wage war on a different battlefield - in the courts. There, they ask: do dioxin-laden herbicides constitute chemical weapons? If so, who should be held accountable in the wake of, allegedly, the largest chemical warfare operation in history? The Last Ghost of War includes interviews with some of the plaintiffs in a class-action lawsuit as they seek justice and compensation from 37 U.S. chemical companies charged with introducing Agent Orange into Vietnam's food chain and, some argue, the gene pool, with tragic results. Narrated by Kevin Kline, The Last Ghost of War explores themes of moral responsibility and corporate accountability while presenting the differing viewpoints on this multifaceted story. This moving and thought-provoking documentary is the third film in a trilogy chronicling the legacy of the Vietnam War.
