From the description:
"Deep in the Rocky Mountains, a gruesome discovery--hundreds of mummified bodies--stirs international attention and fervent controversy. Despite doubts about the bodies' origins, the local Native American Heritage Commission lays claim to the prehistoric remains, along with the strange artifacts found in the same cavern: gold plates inscribed with an unfathomable script.
During a riot at the dig site, an anthropologist dies horribly, burned to ashes in a fiery explosion in plain view of television cameras. All evidence points to a radical group of Native Americans, including one agitator, a teenage firebrand who escapes with a vital clue to the murder and calls on the one person who might help--her uncle, Painter Crowe, Director of Sigma Force."
