Ford, an old boyfriend of Buffy's comes to Sunnydale and, unknown to her, is part of a secret sect which worships vampires. While the others in the sect are misguided teens who believe that vampires are a higher order of life, Ford has a more sinister reason for his deciet. Because he is going to die soon of cancer, he makes a deal with Spike to hand over Buffy in return for eternal life.
Buffy Summer's journey as the Vampire Slayer begins when she moves to Sunnydale, a small Californian town that, unbeknownst to most residents, sits atop a Hellmouth - a portal to supernatural forces. She is discovered by Rupert Giles, the school librarian and her Watcher, whose role is to guide and train her as the Slayer. Alongside Giles, Buffy forms an eclectic group of friends, her "Scooby Gang", including Willow Rosenberg, a shy but highly intelligent witch; Xander Harris, Buffy's best friend and comic relief; and Cordelia Chase, a popular girl who becomes a reluctant ally.
Buffy's relationships with those around her, particularly romantic entanglements, are a major focus of the series. Her most notable love interests are Angel, a vampire with a soul, and Spike, who, despite being a villain, develops a complex and evolving bond with Buffy. The complexities of her relationships, particularly her love life, highlight the emotional weight of Buffy's duties as the Slayer and her desire for connection, love, and a sense of normalcy.
