Martha was only 5 when she and her parents were lured away from their Inuit village. Along with a handful of other families, they were moved to Canada’s most northerly island, Ellesmere, to ensure Canadian sovereignty in the Arctic. They were told that game would be plentiful and life would be easy. Instead, they discovered that the islands of the Arctic are among the least hospitable to human life in the world. For years, they endured hunger and extreme cold. Deprived of the right to an education and a childhood, Martha had to help her family survive. Yet she proved as resilient as the other people from her community who appear in the film. Martha of the North is the story of a journey and a childhood spent in a new and unwelcoming land.

In the summer of 1953, the Canadian government relocated seven Inuit families from Northern Quebec to the High Arctic. They were promised an abundance of game and fish, with the assurance that if things didn't work out, they could return home after two years. Two years later, another 35 people joined them. There they suffered from hunger, extreme cold, sickness, alcoholism and poverty. It would be thirty years before any of them saw their ancestral lands again. Interviews with survivors are combined with archival footage and documents to tell the poignant story of a people whose lives were nearly destroyed by their own government's broken promises.

In the '60s, the Mushuau Innu had to abandon their 6,000-year nomadic culture and settle in Davis Inlet. Their relocation resulted in cultural collapse and widespread despair.
