Angel (season 1)
At the end of the third season of "Buffy", the 242-year-old, re-ensouled vampire Angel left Sunnydale to give teenage Slayer Buffy Summers the chance to live a normal life. Angel is now living in the big city of Los Angeles. With Buffy gone Angel is now completely cut off from society, every day getting closer and closer to giving in to his vampiric hunger. It's not until he befriends the half demon and fellow Irishman Doyle, who is sent visions of people in trouble by The Powers That Be, and fellow Sunnydale resident Cordelia Chase, who grounds Angel's life in the humanity around him, that he truly begins to take charge of his life and seek atonement for his past sins. He sets up his own detective agency, Angel Investigations and begins to "help the helpless".
City Of
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 Gypsies 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.
