Angel, a 240-year old vampire cursed with a conscience, haunts the dark streets of Los Angeles alone. But after he meets a half-demon with mysterious visions, Angel realizes his true purpose: to help those in danger with the hope that he may have a chance to redeem himself and save his own soul. With Cordelia and Doyle at his side, he forms Angel Investigations. He is soon joined by Wesley, Gunn, Lorne and Fred, and he will need all their expertise to fight the growing forces of evil, and the supernatural law firm of Wolfram and Hart.
Fred solves a puzzle for a group of demons who literally want to buy her brain; Angel is hired to clean out a vampire nest by a man who can't afford to pay for Angel's services; Wes and Gunn help a woman whose dead boyfriend is stalking her.
After Cordelia returns, she doesn't remember her friends and Lorne senses a major evil brewing. Scared by the world of demons and vampires, Cordelia takes refuge with Connor, who saves her from a demon attack.
