|This article is about a/an episode in Himitsu Sentai Gorenger.|
The first episode begins at the Kanto EAGLE base, where Tsuyoshi Kaijo and his team are practicing soccer. Suddenly, the symbol of the Black Cross Army is thrown into the ball from out of nowhere. As the soccer team examines the symbol, the Black Cross Army, led by Gold Mask, attack and kill everyone but Tsuyoshi, who witnesses the EAGLE base's destruction. Entering one of the buildings, he finds his injured older brother, who with his dying breath tells him about the Black Cross Army's sneak attack.
Meanwhile, at the Tohoku, Kyushu, Hokaido, and Osaka EAGLE bases, the Black Cross Army attack, but one member from each base survives. As the Black Cross Army celebrates the end of EAGLE, Tsuyoshi recruits the survivors--Akira Shinmei, Daita Ooiwa, Peggy Matsuyama, and Kenji Asuka--bringing to the top secret Gorenger HQ on the 2nd floor of the SnackGon restaurant. The team then heads out to rescue a bus of children who were locked in a warehouse with a bomb. Akira and Daita pilot the Variblune and rescue the children before the bomb explodes.
The team chases down Gold Mask and transform into the Gorengers; Tsuyoshi transforms into Akarenger, Akira into Aorenger, Daita into Kirenger, Peggy into Momorenger, and Kenji into Midorenger. After the Gorengers defeat the Zolders, Gold Mask tries to escape, but the team destroys him with the Gorenger Storm. Shortly after, the Black Cross Army's leader, the Black Cross Führer, learns about the Gorengers.
