Rededicated to the Slayer mission, Buffy is reducing the zompire population one by one - until she is ripped from the middle of a battle and transported to LA. The demon Illyria and a mystical council make the Slayer an unwilling recruit in a team formed to take down an increasingly powerful enemy, the Siphon. Having regained his strength after a brutal battle with Buffy, he's back in action, gathering power and endangering whatever remnants of magic linger in the world. Meanwhile, in San Francisco - unbeknownst to Buffy - the loss of magic is hitting closer to home than ever.
