Wildlife cinematographer Nobuaki Hirano is called to the outskirts of Tokyo to investigate a strange autumn occurrence: hornet nests are being attacked and plundered. But by what? In the forests of Okutama, Hirano finds nature's drama always on display as he films the fall foliage and an array of wild animals. Bears and monkeys come down from the hills to feast on fruits in local villages. A species of bird actually encourages angry ants to attack and bite it over and over again. Look out!
