This engaging doc told largely through archival 16mm footage charts the birth of modern environmentalism and explores how Greenpeace developed from a small group of idealistic environmentalists into a sophisticated movement.

Eco-organization Greenpeace has boots on the ground all over the world. But their origin story begins in 1971, when a group of activists sailed on an old fishing boat from Vancouver to Amchitka, Alaska for one goal — to stop then-President Nixon’s atomic bomb tests.

Based on memoirs by eco-activist and Greenpeace co-founder Bob Hunter, this inspiring film won two Canadian Screen Awards and the documentary editing award at the Sundance Film Festival, for its skillfully layered storytelling.
