The series narrative follows Buffy Summers (played by Sarah Michelle Gellar), the latest in a line of young women chosen by fate to battle against vampires, demons, and the forces of darkness as the Slayer. Like previous Slayers, Buffy is aided by a Watcher, who guides and trains her. Unlike her predecessors, Buffy surrounds herself with a circle of loyal friends who become known as the Scooby Gang.";
