Teenager Phil Dino is not having the greatest time of his life. His schoolmates tease him, his crush ignores him, and his dream of becoming a veterinarian shatters against the Dino family’s occupational tradition: he is expected to become a paleontologist. Phil’s life changes drastically when he accidentally opens a portal to the Mesozoic Era. Now he has to learn to survive in a prehistoric jungle teeming with danger, and to avoid becoming a snack for hungry dinosaurs. Most importantly, he must find common ground with his father so they can prevent a disaster from happening: a giant ancient serpent Megaloboa, who has hated the Dino family for generations, is out to get them.
