Life as a rock star is alluring. People cater to a celebrity; every whim is fulfilled and every indiscretion is overlooked. It is too much for a high school senior from Hampton, NH to resist. Allie is troubled by Mike's changing personality, but her friends reassure her it is temporary. A research paper for his Mike's Anthropology class prompts the crews to travel back in time to find out why a Stone Age city was suddenly abandoned. In the city they meet a charismatic visionary named the Navigator who is realizing his ambitious dreams. The mission would be a lot safer if the Navigator's people were not head hunters.
