In the bustling city of Megalopolis, six dinosaurs are thawed from preservation in the basement of a museum when young paleontologist and tech prodigy Edgar Chudley accidentally triggers a citywide blackout. A year later, Edgar learns that four of the dinosaurs have been living and training themselves in kung‑fu within the museum’s basement. The four, now skilled martial artists, become friends with Edgar, and together they set out to thwart the plans of the remaining two dinosaurs, raptor brothers Skor and Skrap. Skor, who is evil, and Skrap, who is dimwitted, hunt for crystals containing mutant DNA. With this DNA, Skor intends to create monstrous dinosaurs to conquer the world.
