The Power Rangers always save the day, but have they ever faced a force this evil? When a devious paleontologist releases his mutant Dino Zords, the Black Power Ranger must dig into his mysterious past to find a way to stop these creatures of unbelievable resources. Along the way, he finds three unassuming students to induct as new Rangers -- a soccer player, a musician, and a gamer -- but can he train them in time to stop the Dino Zords?
A trio of teenagers are trained as Power Rangers in order to defeat a devious paleontologist's dinosaur creations called Dino Zords. While on a fossil-finding field trip, three Reefside High students--Conner, Kira and Ethan--fall into a sinkhole and discover powerful Dino Gems that give them each super abilities. But alarming evil is afoot as this new crew is confronted by terrifying Tyranodrones, Kira's sudden disappearance and Mesogog, a reptilian rogue and his robotic wrongdoers. Once Mesogog has unleashed his diabolical Zords, the teens' teacher and mentor, Dr. Tommy Oliver, has no choice but to return to his past as the Black Power Ranger and morph them into full-fledged Rangers ready to tame the mutant terrors.
