When world peace is threatened by the emergence of a terrorist group called the Black Cross Army, EAGLE (The Earth Guard League) is formed to combat the threat. The Black Cross Army sends five operatives to destroy each EAGLE branch in Japan, killing all but five members. These surviving members are summoned to a secret base located underneath the snack shop "Gon", where they are recruited by EAGLE Japan's commander, Gonpachi Edogawa. They become the Himitsu Sentai Gorengers and are given electronic battlesuits that endow them with superhuman strength and speed. The five dedicate themselves to stopping the Black Cross Army and its leader, the Black Cross Führer.
