Buffy experiences Big Bad Twilight's overwhelming reach through the strange and sudden mass popularity of vampires (they even have a spokesperson with a reality TV show, Harmony Kendall!) that leads Buffy and her Slayer army to come under public scrutiny. As the world's distaste for Slayers grows, Buffy takes her troops to a refuge in the Tibetan mountains, where she hopes to receive some help from longtime friend - and werewolf - Oz. Buffy faces the ultimate betrayal and suffers through sacrifice as she scrambles to finally put an end to Twilight and save the world from complete destruction.
