Fourteen-year-old Shannen Koostachin launched a campaign to build a suitable school for the children of the Cree community of Attawapiskat in 2008. Two years later, tragedy struck when Shannen was killed in a car accident. Her campaign became a national movement, bringing people from all walks of life together to make Shannen's Dream--the dream of fairness in education for First Nations children, in schools that are safe and welcoming--a reality. With the documentary Hi-Ho Mistahey!, Alanis Obomsawin brings together the voices of those who have taken Shannen's Dream across Canada and all the way to the United Nations in Geneva, in a larger-than-life adventure. In February 2012, a motion on education for First Nations children passed unanimously in the House of Commons. The voice of the children had been heard, and construction of a new school in Attawapiskat could finally begin.
