The series premiered on March 10, 1997, on The WB and concluded on May 20, 2003, on UPN. The series narrative follows Buffy Summers (played by Sarah Michelle Gellar), the latest in a line of young women known as "Vampire Slayers", or simply "Slayers". In the story, Slayers are "called" (chosen by fate) to battle against vampires, demons, and other forces of darkness. Like previous Slayers, Buffy is aided by a Watcher, who guides, teaches, and trains her. Unlike her predecessors, Buffy surrounds herself with a circle of loyal friends who become known as the "Scooby Gang".
