Arctic Defenders tells the remarkable story that began in 1968 with a radical Inuit movement in Canada. It led to the largest land claim in western civilization, orchestrated by young visionary Inuit with a dream - the governance of their territory - the creation of Nunavut. The story reveals the dark side of Canada's attempt at sovereignty in the north and finds hope and inspiration from determined Inuit who changed the rules of the game. It's also an incredibly personal film, as it charts Walker's return to the High Arctic which he first explored as a wide-eyed teenager.
