Having been reintroduced to Yellowstone in 1995 after a 70-year absence, wolves have reignited an age-old battle between predator and prey. The Wapiti Pack, the largest in Yellowstone, has earned a reputation for ferocity. Now a young, lone wolf, “Blacktail,” seeks to join their ranks as they master the art of taking down a mighty bison. But wolves aren’t the only force keeping Yellowstone’s herds in check. The endangered Yellowstone grizzly population has made a remarkable comeback, rising from a low point of fewer than 150 bears to more than 700 today. Many are descendants of legendary matriarch “Quad-Mom,” who, at more than 20 years old, is raising two new cubs – perhaps the last of her litters. She must defend the cubs against giant boar grizzlies and teach the cubs to hunt newborn elk. As the family ventures to the high alpine in search of a rare treat, darkness descends on Yellowstone during a total solar eclipse.
