Buffy and Riley are spending all their time in bed (and they're not sleeping). Their round-the-clock exploration of each other awakens the spirits of children who were sexually repressed by their foster mother back when Lowell House was a home for orphaned and runaway kids. Willow, Giles and Tara divert the angry children while Xander and Anya go to try and stop Buffy and Riley.
"Into every generation, there is a chosen one. She alone will stand against the vampires, the demons, and the forces of darkness. She is the slayer".
When a young vampire slayer by the name of Buffy Summers, moves to Sunnydale, California, she quickly finds out that Sunnydale is located right on top of the Hellmouth - the center for all evil activity. Her new watcher, Rupert Giles, also happens to be the school librarian. It is his job to train her and guide her in all the skills she needs to be a Slayer. She and a group of close friends, commonly referred to as "The Scooby Gang", help her in her battle against evil.
