The Appalachian Mountains are a region of incredible beauty and amazing legends. One such legend tells of a terrifying giant with a 7-clawed hand who left his mark on a massive rock. This incredible rock is sacred to Cherokee people who revere the artifact for its intriguing symbols and cultural significance. Others say the symbols aren't Native, but may be connected to visitors from afar--perhaps from over the ocean or from another world. Trying to set the record straight on this controversial stone, Scott Wolter heads to Appalachia. As Scott tries to determine the age of the carvings, he discovers the stone may have strange and mystical powers. He also learns that this isn't the only massive artifact in the region--the connection between the two may lead to a "giant" conclusion.
