Defensora is a documentary about a Mayan Q'eqchi' resistance against mining in Guatemala. The story is set along the shores of Lake Izabal in the community of El Estor where a nickel mining company has operated for over 50 years. Tensions run high against a backdrop of pro and anti-mining camps, violence and forced evictions. The film takes audiences into the lives of defenders in the resistance who struggle to reclaim their ancestral lands and seek justice in Canadian courts for alleged human rights violations.
