Sunnydale High is re-opened, with a new designed campus and a new principal, Robin Wood. It is Dawn's first day at school there and Buffy accompanies her to class, only to discover evil spirits lurking in the basement.

A giant worm-like creature begins stalking a young woman. As the gang begin to investigate, they realise it's appearance in Sunnydale may be linked to Anya.

Willow's return proves problematic when she is literally unable to see her friends--and is left with a creature that paralyzes its victims.

Buffy begins a new job as school counsellor at Sunnydale High. On her first day she encounters a troubled young girl who is convinced she is about to die.

Anya's violent and deadly act of vengeance leaves everyone stunned. Buffy must put aside her feelings and take action before more people die.

Xander and Spike search for the source of a spell that has bewitched the girls into competing for the affections of the high school quarterback.

Buffy strikes up a conversation with a vampire who was once an acquaintance in high school. Dawn defends Joyce from a menacing creature.

Buffy and her friends fear Spike may be to blame when a number of people around town mysteriously disappear.

Buffy hopes to learn more about what she's up against with the First by taking Spike prisoner; Xander and Anya interrogate Andrew.

Giles returns to Sunnydale with three potential slayers, whom Buffy must protect from The First. Meanwhile, a ferocious Uber-vampire is released from the Hellmouth and Buffy must kill it before it kills one of the potentials.

Buffy has to keep the ever increasing number of potential Slayers from panicking while Giles and Anya seek answers from the Beljoxa's Eye.

Buffy takes the Potentials to a demon bar and then to Spike's crypt, in order to teach them the art of slaying. When Willow casts a spell to seek out the next Potential, the spell leads them to believe that Dawn may be a future slayer.

After Willow and Kennedy share their first kiss, Willow is transformed into Warren, the man she killed last year. When she sets out to find help, she bumps into an old friend. Meanwhile, Buffy searches for answers when Spike's chip causes him great pain, and the gang suspect that Giles may really be The First Evil.

Buffy accepts an invitation to dinner from Principal Wood, and the secrets of his past are revealed. Xander impresses a beautiful girl with his knowledge of rope, and she seems to be interested in tying him up. Meanwhile, the First contacts Andrew in another attempt to destroy the Potentials, and Giles finds himself tongue-tied with the new Potential, Chao-Ahn.

The Scoobies use a spell to transport Buffy into a shadow world, where she meets the men who created the first slayer. However, in order for her to return home, the gang must find and slay a ferocious demon.

Andrew creates a documentary called "Buffy, Slayer of the Vampyres", a record of the current situation in Sunnydale to show to future generations. He manages to capture many important moments, and to annoy almost everyone in the house. But Buffy needs to tear him away from his filmmaking because the Seal of Danzalthar is active and Andrew may hold the key to closing it before it destroys the town.

Robin Wood seeks revenge on Spike for killing his mother nearly 30 years ago, whilst everyone else tries to find out how The First has control over him.

Faith returns to Sunnydale just as a new villain, Caleb, arrives and sends Buffy a message in the form of a badly beaten Potential. Buffy leads the rest of the girls to Caleb and The First's lair, with devastating consequences.

Faith and the Potentials search underground for a weapon, whilst Buffy confronts Caleb at the vineyard.

Buffy has a powerful new weapon, but the gang cannot find any information about the origins of the mysterious scythe. Eventually the Slayer goes herself in search of knowledge, and finds a new ally, an old friend, and great danger.

After killing Caleb, Buffy conceives a plan to defeat the First once and for all. Willow invokes a magic spell that alters the ancient Slayer spell and gives Buffy the allies she needs to fight the Uber-Vamp army. An epic battle ensues and several good friends are lost. At the end, Buffy faces a completely new problem -- one she's glad to have.
