Does Mount Rushmore, one of America's greatest icons of Democracy have a more sinister meaning? Buddy, Mac and Scott travel to Big Sky country to decode the intended message possibly hidden within this great American symbol.

Mass suicides. Human sacrifices. Unholy rituals. Throughout history, people have claimed to have otherworldly knowledge, and have led followers to commit horrific acts of violence. Are they con men? Are they insane? Or might the voices in their heads really be of an extraterrestrial origin? And if so, did they simply misinterpret the messages they received? Or might there be extraterrestrials with a sinister agenda?

This special takes viewers deep inside America in the late 1960s--into a world of hate, fear, sex, and mind-control. It vividly details how Charles Manson transformed a harmless group of hippies--mostly young women from decent families--into a gang of brutal murderers. The two-hour drama-documentary weaves in rare archival footage and on-camera eyewitness testimony to present a spellbinding portrait of a true nightmare in U.S. history. At the center of the film is Linda Kasabian, the star witness for the prosecution, who has emerged from hiding to tell the full story of the murders for the first time in four decades.

From the bizarre prophecies of Charles Manson to the desperate paranoia of Jim Jones, cult leaders draw us into worlds of power, paranoia, and death. Through interviews with world-renowned scholars and the survivors of cultic tragedy, we will unmask the mystery of cults. From Jim Jones' pursuit of a socialist paradise to Warren Jeffs' Yearning for Zion ranch, cult leaders have twisted the quest for purity into an obsession with madness and murder.
