William Shatner explores the theory that the U.S. government is involved in a cover-up of visiting alien spacecraft. Based on a book by Erich von Daniken, this documentary contains evidence of extraterrestrial life here on earth.

Everything from the Peruvian Crystal Skull to the megalith structures in the jungles of Southeast Asia is accepted as evidence for the AAS theory. Cave drawings, old legends, Biblical stories and even some psychic visions of late Jeane Dixon are understood as stone cold facts. Eric von Däniken’s reputation was still quite unspoiled at the time so all the arguments (even the most far-fetched) are shown with a great confidence.
