Sunflower dreams to be a treasure hunter. With Dave’s help, she follows her grandfather’s footsteps and travels to the Jurassic to start a magical treasure hunt. In this era, Sunflower has to figure out how to get along with the dinosaurs. She helps a lost baby Mamenchisaurus to find his mother and escapes from a forest fire with Stegosaurus, and almost becomes food of Yangchuanosaurus. Having dreams is a good thing, but without courage or wisdom, achieving them will be difficult. Can Sunflower make her dream come true in the end?
