Millions of years after the mysterious and powerful Energems were entrusted to the now extinct dinosaurs for protection from a ruthless bounty hunter, a pair of courageous teens find themselves in possession of two of these long lost precious artifacts, and come face to face with a monster who will do everything in his power to steal them for himself.

A new teen finds his own Energem and joins Tyler and Shelby on their pilgrimage to the Dinosaur Museum, where they learn they are a part of the elite team called the Power Rangers. They are entrusted with protecting the Energems from a fierce bounty hunter named Sledge, who has returned and is more determined than ever to capture the Energems for himself.

When one of Sledge's transport pods is spotted in New Zealand, the Rangers head to Auckland and are shocked to discover the existence of a new Ranger.

The Rangers believe their work is done after they've defeated Sledge and his evil monsters. Unbeknownst to them, an even more powerful monster is picking up where Sledge left off and is closer to the Rangers than they think.

The Rangers are forced to go to intergalactic trial for crimes against monsters.

The Rangers learn the history of their Energems from a newfound ally. Meanwhile, an epic battle ensues in the forest over the Silver Energem.
