In the conclusion of a two-part story, the Colonials have fallen under the spell of godlike alien Iblis (Patrick MacNee), who offers them safe passage to the 13th Colony in exchange for their total and unquestioning obedience. Once Iblis successfully brings the treacherous Baltar (John Colicos) to justice, the Colonials have no reason to question their sincerity. But Cmdr. Adama (Lorne Greene) is not so easily swayed--especially after witnessing Iblis' terrified reaction to the three shimmering balls of light which seem to be dogging his trail. A climactic confrontation with the Forces of Darkness caps this thrilling adventure.
