In 1971 a small group of activists set sail from Vancouver, Canada in an old fishing boat.

Their mission was to stop Nixon’s atomic bomb tests in Amchitka, a tiny island off the west coast of Alaska. It was from these humble but brave beginnings that Greenpeace was born. Chronicling the untold story behind the modern environmental movement and with access to dramatic archive footage that has not been seen for over 40 years, the film tells the fascinating story of eco-hero Robert Hunter and his part in the creation of what we now know as the global organization that is Greenpeace. Alongside a group of like-minded and idealistic young friends in the ‘70s, Hunter would be instrumental in altering the way we now look at the world and our place within it.

These campaigning pioneers captured their daring and sometimes jaw-dropping actions on a range of film cameras and Greenpeace granted Rothwell access to this vivid archive to make his thrilling, sometimes terrifying film.

Premiering at the Sundance Film Festival it tells an important story that is still very relevant today making this one of the must-see documentaries of 2015.
