Supernatural gang warfare forces Buffy and her friends to enter Angel's turf in Los Angeles, even as both Angel and Cordelia discover their own problems with vampire-worshipping cults and havoc in the local prisons.
In Los Angeles, Angel and Buffy compare notes and realize that both are dealing with cases of missing teenagers -- most of them children of the rich and powerful. Coincidence? They don't think so. But when Buffy checks in with Giles, she learns that primetime doomsday has hit Sunnydale, taking precedence over the gang warfare in L.A. Back in her hometown, Buffy finds the doorway through which the monsters are gaining allaccess passes to our universe. Renegade scientists have discovered how to open the portals from one reality to the next, which could explain where the teens are hidden. But when you're operating near a hellmouth, opening dimensional portals is tricky business: you never know who -- or what -- you're going to attract. With the lives of the kidnapped teens and one dangerously talented young woman at stake, Buffy and Angel join forces to do battle in the uncharted dimension....
Buffy and Angel venture into a terrifying alternate reality populated by dragons and other legendary monsters to rescue a group of kidnapped teens, only to discover that Spike and Faith have also journeyed through the portal.
