After moving to Sunnydale, California, Buffy Anne Summers just wants to be a normal teenager. Back in Los Angeles, her first Watcher had died; she inadvertently burned down the gymnasium at her old high school; and her parents got a divorce. The move to Sunnydale is supposed to give both her and her mother, Joyce, a clean slate. But then she meets the school librarian, Rupert Giles, and quickly learns there is no escaping her destiny. With Giles as her new Watcher, she reluctantly steps back into her role as the Slayer. But this time she is not fighting alone. She now has an inner circle of special friends — Willow, Xander, Cordelia, and a mysterious young man named Angel — ready to join the fight and drive in a stake or two if need be.

Mr. Church reunites the Expendables for what should be an easy paycheck, but when one of their men is murdered on the job, their quest for revenge puts them deep in enemy territory and up against an unexpected threat.

New vampires Spike and Drusilla come to town along with the new slayer, Kendra Young, who was activated as a result of Buffy's brief death in the season one finale. Xander becomes involved with Cordelia, while Willow becomes involved with witchcraft and Daniel "Oz" Osbourne becomes a werewolf after being bitten by a young cousin who just happens to be a werewolf. Buffy and the vampire Angel develop a relationship over the course of the season, but Angel's dark past as the evil and sadistic Angelus threatens to destroy Buffy and the world.

Buffy returns from the big city to find her friends have been battling the forces of evil without her. As she struggles to regain her mother's and her friends' trust, a new slayer named Faith arrives in town, quickly winning over all of Buffy's friends. But Faith's arrival is just the beginning of new forces Buffy must face. For a few nights later she encounters Angel, who has somehow returned, feral and violent from the hellish demon dimension where Buffy had sent him. But the real demon Buffy must ultimately face is already on this side of the portal, preparing a special graduation day surprise for Sunnydale High.

Angel, the dashing demon from Buffy the Vampire Slayer, embarks on his own supernatural adventures in Los Angeles. City of Angels. City of Broken Dreams. Between pervasive evil and countless temptations lurking beneath the city's glittery facade, L.A is the ideal address for a fallen vampire looking to save a few lost souls and, in turn, perhaps redeem his own.

Emma, a kind-hearted foster kid who can't catch a break, finds out she has an identical twin sister, Sutton, who — unlike Emma — was adopted by wealthy parents and is seemingly living an ideal life. After their initial meeting, Sutton talks Emma into stepping into her life for a few days while she pursues a lead on their birth mother. Initially excited to do this favor for her sister, Emma soon learns that Sutton has gone missing and could be in trouble. Now, Emma must decide whether to come clean to Sutton's family and risk her own safety in the hope of uncovering her twin sister's true whereabouts, along with the truth about why they were separated in the first place.
