Casey Templeton is in a bind when he must foil a burglary of dinosaur bones. While helping with a real dinosaur dig at the world-famous Royal Tyrrell Museum, Casey Templeton finds a piece of dinosaur tooth. Excited, he spends all afternoon looking for the rest of the tooth, but all he ends up getting is a nasty sunburn. Lying in his hotel room that night, trying to recover, he sees and hears two men in a nearby room planning a robbery of precious artifacts from the Tyrrell. Later, Casey tells the museum's curator (and old family friend), Dr. Norman, what he has seen and heard. Dr. Norman hires Casey to keep a watch out at the museum for the robbers. No luck. As the summer comes to an end, Casey and his friend Mandy decide to relax and take a bicycle jaunt north of Drumheller. But on the road they accidentally meet up with the conspirators and soon find themselves in a grim situation. Casey has to use all his ingenuity and skills to escape so he can try to help thwart the planned heist. Can he do it?
