Grey Owl.

Archie Grey Owl is a trapper in Canada in the early 1930s when a young Iroquois woman from town asks him to teach her Indian ways. They live in the woods, where she is appalled at how trapped animals die. She adopts two orphaned beaver kits and helps Archie see his way to stop trapping. Instead, he works as a guide, a naturalist writer, and then the Canadian government hires him to save the beaver in a conserve by Lake Ajawaan in Prince Albert National Park. He writes a biography, which brings him attention in Canada and invitations to lecture in England. Before he leaves, he and Anahareo (Pony) marry. In England, his secret is revealed. Will Anahareo continue to love him?
