Angel

Fred and Gun frantically hunt for clues to their friends' whereabouts, the only eyewitness to Angel's plight is murdered, and an unlikely person rescues Angel.

Angel, Fred and Gunn run into a cat burglar while trying to steal a mystical antique that can locate lost souls across dimensions.

While in Las Vegas, Angel discovers that Lorne is being coerced by a casino owner to steal the significant destinies of patrons to sell on the black market.

Cordelia returns, but she has no memory of who she is or that Angel is a vampire, so everyone tries to keep the demon-hunting business a secret.

A portal opens at the symposium where Fred is speaking on her recently published physics article; she comes face to face with a former professor's dark secret.

While restoring Cordelia's memory, Lorne inadvertently causes everyone to revert to their high-school personas and to forget what they know about each other.
