[Xander, Giles, Buffy, Cordelia, and Willow, aka The Scooby Gang]

In this first season of Buffy, we meet the Scooby Gang (see above) who work with Buffy to fight the Master, an ancient vampire. The Master is caught in the very mouth of hell (conveniently located beneath the library at Sunnydale High School) and works to be free. His ultimate rise from Hell is predicted in the Pergamum Codex, an ancient book of prophesies about the Slayer.

While the Master's efforts to break down the wall that keeps him below ground appear throughout the season (and form the central action of the final episode), there are also episodes with "monsters-of-the week," such as demons and witches. More importantly, we also meet the mysterious Angel, the vampire with a soul who has pledged to help Buffy (and ends up falling in love with her and she with him).

As the Master's plot line unfolds, we see him sending out his vampire devotees to gather victims to feed him; there is also a child known as the Anointed One, whose purpose is to bring Buffy to the Master.
