Angel is an American television series, a spin-off from the television series Buffy the Vampire Slayer. The series was created by Buffy's creator, Joss Whedon, in collaboration with David Greenwalt. It aired on The WB from October 5, 1999, to May 19, 2004, consisting of five seasons and 110 episodes. Like Buffy, it was produced by Whedon's production company, Mutant Enemy.
The show details the ongoing trials of Angel, a vampire whose human soul was restored to him by gypsies as a punishment for the murder of one of their own. After more than a century of murder and the torture of innocents, Angel's restored soul torments him with guilt and remorse. During the first four seasons of the show, he works as a private detective in a fictionalized version of Los Angeles, California, where he and a variety of associates work to "help the helpless", restoring the faith and saving the souls of those who have lost their way.
