Throughout history, whenever the world needed heroes, seven kids with the purest hearts were chosen to be the Rainbow Riders. Gifted with the powers of the dinosaurs, whenever and wherever they are needed, the Riders are whisked away on a rainbow to fight crime and social injustice. Rainbows have always been used to transport the Riders, which is why you can never find the end of the rainbow.

In this story, Rene, Alya, Isiah, Nayela, Bobby, Omma, and Wink get their dino-powers and are soon tested when they are magically transported by a rainbow to thwart a bank robbery in progress. They quickly discover that only by working together, putting their differences aside, using their unique individual skills, and having faith in their teammates, will they be able to stop the dangerous gang of villains without letting innocent people get hurt.
