After the five investigators get stuck in a small city because their car breaks down they go to an event where a dinosaur bone that just has been found is presented. After a man (Marty) storms the scene and claims that his father has found the bone, the five investigators go on an adventure to find the place where Martys father found the bone to prove that he is the rightful discoverer. But other people are looking for the dinosaur bones aswell.—Will-Graham
