Ryan and Kelley think that being teamed up for a school science project will be a disaster. Ryan is too busy constructing his "living dinosaur village" to waste time on a boring university fossil dig. And Kelley, who wants to prove herself to her scientist father, fears that Ryan's wild imagination could ruin her grade. But the fossil dig is anything but boring. Someone is sabotaging the site, and Ryan overhears a suspicious conversation. When he finally convinces Kelley that they need to investigate, they discover that dinosaurs might not be extinct after all!
