One of Buffy's decoy doubles recalls how she was called upon and trained to be a slayer. The heroic young woman's undercover assignment takes her deep underground, where she leads a stand against Yamanh and his demonic horde.

Faith is approached by Giles with a dangerous assignment—to pose as a British aristocrat in order to assassinate a wealthy, rogue slayer under the tutelage of an Irish warlock. Meanwhile, Buffy frets about the coming of Twilight and the meaning of an ominous dream.

Posing as a viscount's daughter, Faith infiltrates Lady Genevieve's gala and is attacked by Roden's gargoyle security team. Elsewhere, Willow offers to Dawn with her plus-sized problem and is called upon to upgrade the castle's defense system. Finally, after bonding with Faith, Genevieve reveals her evil plan.
