Ten million buffalo once roamed the plains of North America. Today, only a few carefully protected herds remain. The carrier pigeon, the whooping crane, the flightless great auk of the Atlantic seaboard, and other species have all fallen prey to the greatest predator, man. This film shows efforts being made by wildlife specialists to preserve and nurture the creatures that do remain in our wilderness areas. Scenes rarely photographed make this a spellbinding film throughout.
