Erstwhile "James Bond" Roger Moore guest stars as Edward Poole, an SD-9 leader who has startling information about a turncoat in the Alliance of Twelve. Elsewhere, Sydney (Jennifer Garner) is not the only one who is astonished to find her own image on a sketch drawn 500 years earlier by the prophetic Milo Rambaldi. The text surrounding the sketch is partially decoded, revealing an ominous message regarding the fate of the world. Alas, the key to the entire code is locked somewhere in the Vatican -- compelling Sydney to prevail upon Vaughn (Michael Vartan) to pull off his most daring burglary. ~ Hal Erickson, Rovi
