Ten-year-old Sophie eagerly anticipates a summer of adventure with her daring Grandma Clara, while her brother Leo, 13, remains skeptical. Clara, a retired biologist, takes them on thrilling escapades to famous sites around her hometown with her sidecar motorcycle. Their summer takes a wild turn when they find dinosaur eggs in the legendary “Dragon Hole” cave. Clara recognizes the pulsing life within, leading to a mission to protect the eggs. Once hatched, these dinosaurs display incredible talents—rapid learning or speaking abilities. As Sophie and Leo bond with their new dino friends, they must protect them from those who would exploit them, turning each day into a game of hide-and-seek.
