As world peace is becoming unbalanced due to the emergence of a terrorist group of masked humanoid machines known as the Black Cross Army. The United Nations ends up establishing EAGLE an acronym for “Earth Guard League” with its main purpose is to combat the Black Cross Army itself. Upon the placing of the EAGLE bases across the country of Japan, the Black Cross Army counterattacked five of the EAGLE bases leaving all of the personnel dead except for five members from each of the five now destroyed bases. The survivors ended up being summoned to EAGLE's secret base which is located under a snack shop. Upon arriving, the five EAGLE personnel were greeted by Commander Gonpachi Edogawa who informs the five personnels that they were chosen to become EAGLE's own superhero squadron known as the Secret Squadron Gorenger. Given the powers of five multi-color electronic battle suits, the Gorengers are Earth's best chance of defeating the entire force of the Black Cross Army.
