Doppelgangland

In which Willow is dead. And kind of gay.

Official back-of-box synopsis:

Doomed to live life as a mortal since her amulet was destroyed by Buffy and the gang, Anya begs with a demon to get her powers back. When she approaches Willow for help, Willow agrees, hoping to shred her reputation as 'Old Reliable'.

From the old WB Buffy website:

A VAMPIRE WILLOW PREYS ON SUNNYDALE - Buffy and the real Willow must save the day when from the bleak alternate universe in which vampires rule Sunnydale, Willow's blood-sucking doppelganger is brought forth into this world and wreaks havoc and confusion on Sunnydale. Meanwhile, Buffy goes into full training mode so she can ace out Faith on the Watchers Council tests, while Faith's unholy new alliance is already paying handsome dividends.
