Synopsis by Hal Erickson
Willie Garson guest stars as Martin Lloyd, a wild-eyed conspiracy theorist and self-proclaimed "space alien". Amidst his ramblings about JFK and the CIA, Lloyd intimates that he might have the "lowdown" on the Stargate program. Just to cover all bets, General Hammond (Don S. Davis) asks O'Neill (Richard Dean Anderson) to investigate Lloyd's claims. Prepared to dismiss Lloyd as a harmless crackpot, O'Neill is compelled to change his mind by a subsequent series of bizarre and deadly occurences.
