In 2012, the Olympic Games included women’s boxing for the first time in history. But, only three weight categories would be admitted - 51kg, 60kg and 75kg. To compete for their Olympic dream, women boxers all over the world were forced to move up or down in weight in order to qualify. For two of the world’s best fighters, both from Canada, this meant the end of a friendship and the beginning of a fierce rivalry. Last Woman Standing follows elite female athletes, Ariane Fortin and Mary Spencer, as they end a decade long friendship in order to fight for one position on the Canadian team and the opportunity to make history as one of the first women to box at the Olympics.
