The young student Hui (played by Arisa Nakamura) is not only beautiful, but also has sharp karate skills. On this day, Hui and a group of old friends, a group of five people, went to the woods to relax. The five people were fishing in the woods, but they found a strange parasite on the fish. Then, when they went to the toilet, they were attacked by zombies. The young people who were scared to death found the home of Dr. Tanaka and his daughter, and ran in to take refuge. But they didn't know that the terrifying parasites and zombies were Tanaka's test subjects. What is the connection between parasites and zombies? Can Hui's karate help her friends escape?
