High schooler Jinguu Masato has always had an affinity for animals. Because of that, he always visited the zoo and even came to befriend the elephant, Hanayo. Now that he’s back for the first time in 7 years, the zoo has changed to Fuji Safari World, where customers can get up close to the animals. But the zoo has changed in many, more horrific, ways. When Masato brings his old friend Hitomi to visit, they discover zookeepers being attacked by the animals. By the time they find Hanayo’s caretaker, Nakata, they realize the disturbing truth of the animals now having the faces of humans! Now the animals are out for revenge for being cruelly experimented on -- by eating humans!
