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.
The Angel Investigations team is stunned when the Senior Partners of Wolfram and Hart give them control of the L.A. office. The gang quickly moves in, and although everyone is delighted at the amazing resources they now have at their command, they can’t stop wondering what the catch is.
Angel continues to seek redemption in season two, but a fatal mistake makes him realize that racking up the body count isn’t the way to go. So with a renewed sense of purpose and Cordelia, Wesley and Gunn at his side, Angel sets out to make the streets of Los Angeles a little safer for everyone — unaware that Wolfram & Hart has summoned someone from his past to make sure he fails.
Even as Angel mourns the death of Buffy, Darla makes her way to L.A. with a mysterious new life growing within her. Now thrust into a role he never imagined, Angel needs the assistance of the Angel Investigations team more than ever. But while Cordelia, Gunn and Fred rally round the new dad, an ancient and deadly prophecy convinces Wesley to commit the ultimate betrayal.
With both Angel and Cordelia still missing, Fred, Gunn and Connor try to keep Angel Investigations running while they search for their friends.
