Keeper, the guardian of the Energems, fled to Earth, where he entrusted the Energems to the dinosaurs for protection. After the dinosaurs went extinct, the Energems were lost. Now, Sledge is back, and it's up to the teen heroes known as the Power Rangers Dino Charge to hunt down the missing Energems and defeat the vicious Sledge — once and for all!
