Trapped in Photomare's picture, the Rangers turned little kids are helpless. Young Bulk & Skull come to their rescue, stealing the picture and evading Goldar. They try to convince Mr. Kaplan (who has HAIR in this reverted time period) of their story, and he throws them into detention.
Alpha 5 knocks the two little bullies out, takes the picture, and removes the Powerless Kids from captivity. After convincing them of the truth, the six children allow Alpha to use a device to restore their ages to normal.
Back to their normal ages, the Ranger Teens morph, fight Photomare (who makes a copy of the Red Dragonzord during the Megazord battle), and race to destroy the Rock Of Time. When it's destroyed, Earth's rotation returns to normal, time flows properly again, and the world is saved.
