Looking for a movie where a family goes to the mountains to learn about wolves I think and the mother and father die in bear attack the little girl survives and grows up with wolves. Fast forward to adult hood she still there doesn't speak and lives like wolf a trapper is trying to get her and a ranger comes and finds her befriends her and saves her from the trapper
