Somehow, the hell-hole must be found and corked at its source. For Buffy, Angel, and the rest of the gang, that means a road trip to Boston where an ailing Gatekeeper resides over a supernatural mansion that has been, until recently, holding the world's worst monsters at bay. Once there, Buffy discovers the catastrophic truth: the magical structure houses thousands of rooms, all of which are doorways to limbo's "ghost roads," and all of which may bring her face-to-face with the most nefarious forces in hell and on earth--forces bent on horrific plans far worse than the Slayer ever imagined.
