As the first wolves reintroduced into Yellowstone, the Druids are the most celebrated wolf pack in North America. New pioneers in the wilderness, they were at the heart of a massive scientific experiment to restore an entire ecosystem that began to break down without its wolves. Emmy Award-winning filmmaker Bob Landis spent over three years with these remarkable wolves, creating a spectacularly dramatic and intimate record of their lives, their great battles with rival wolf packs, and the changing fortunes of the coyotes and foxes who share their home range in Yellowstone's beautiful Lamar Valley.
