Oz comes to town to give Angel the gem of Amarra, courtesy of Buffy. The ring makes any vampire impervious to stakes, sunlight, etc... You would think Angel would like having this gem, but he ends up hiding it. Enter Spike. Seems Spike followed Oz to town and wants to get the ring back. (he did all the work for it, right?) Spike makes his presence known pretty quickly and ends up having Angel tortured by a VERY strange and sadistic vamp so Angel will give up the whereabouts of the ring. Cordy and Doyle search for the ring and Doyle finds it. They cut a deal with Spike to return the ring to him and get Angel back. With some help from Oz, they get Angel away from Spike and the weirdo Vamp. Spike aint happy, but is even LESS so when he sees the ring is gone. The psycho vamp took it. Angel ends up retrieving the ring and he does take one turn wearing it so he can experience being out in the sun and also watching the sunset. Then he destroys it, knowing no good can come from him having it.
