The evil secret society known as the Telephone Pole Gang seeks to take over the world by first taking over a certain prefecture on Kyūshū (they never specify which one). In order to thwart the evil plans of the Telephone Pole Gang, Imazuru High School creates the Prefectural Earth Defense Force, composed of problem teachers and students from the school. They are also joined by a cyborg transfer student from India.

High School student Gen and his girlfriend Oshimi are kidnapped by the space pirate Lipmila. 20,000 years ago, other aliens hid an ancient and priceless map on Earth. Gen knows how to find it - or so they tell him.
