Set on a mountain, in an anonymous village along the Trans-Canada highway, "Caribou "is a stark, unrelenting character study of two hunters in a savage October of the heart. Louis, a construction worker and husband, must negotiate his brother-in-law Duncan, mentally deficient since birth and dependent on him and his wife, Anne. One day, he and Duncan embark on a hunting trip. It is a last chance for both men, driven to the limit by love, each willing to kill for their right to exist.
