"City Of is the series premiere of the television series Angel. Written by co-creators Joss Whedon and David Greenwalt and directed by Whedon, it was originally broadcast on October 5, 1999 on the WB network. Angel (David Boreanaz) was a character in the first three seasons of Buffy the Vampire Slayer. Angel had been a soulless, immortal vampire who was legendary for his evil acts, until a band of wronged Romani punished him in the 19th century by restoring his soul, which overwhelmed him with guilt over his past actions. In the third-season finale, Angel leaves to go to Los Angeles to get away from Buffy, whom he loves but can never be with. In Los Angeles, he meets Doyle (Glenn Quinn), a half-demon who is sent visions by the Powers That Be about people whom Angel is supposed to rescue from danger. Acting on Doyle's first tip, Angel encounters Cordelia Chase (Charisma Carpenter), who has moved to L.A. from Sunnydale (where Buffy the Vampire Slayer takes place) to pursue a film career. Cordelia convinces Angel that she, Angel and Doyle should start up an agency to help people having supernatural or demonic problems. Plot While drowning his sorrows at the bar of a dive in downtown Los Angeles, Angel notices three guys leave the bar with two women. Angel unobtrusively follows them to a dark alley, where he kills the three men, who are revealed to be vampires. One of the frightened girls, Janice, bleeding from a minor head wound, tries to thank him, but Angel, fixated on the blood, warns them harshly to get away from him, and strides down the dark alley. Angel makes his way to his new home, a basement apartment beneath a ground floor office, where he finds Doyle waiting for him. Doyle introduces himself, explaining he is half human, half demon, then recaps the story of Angel's life, ending with his recent, painful breakup with the Slayer and his subsequent move to L.A. Doyle explains that Angel's isolation, combined with the fact that he recently drank human blood, puts him at serious risk of relapse. Doyle gets visions from The Powers That Be (accompanied by debilitating headaches) regarding people whose lives Angel must touch; true redemption lies not just in saving lives, but in saving souls as well. Doyle concludes by handing over a scrap of paper on which he has jotted information
