Sulking around the Slayer in Sunnydale, the vampire Spike has often run into demons intent on punishing him for throwing in with the White Hats. But when there are hints of a more organized campaign dedicated to vanquishing the vampire with a chip in his head, Spike sets off on the trail of whoever's put a hit on him. Meanwhile, in the City of Angels, the vampire with a soul finds that the search for a mystical object is tied to his days as the vicious Angelus. Then Spike - his former partner in carnage - arrives in L.A. Each nursing a grudge, and with the spectre of Buffy in both of their (cold, dead) hearts, the two vampires reluctantly work together...until their tortuous past catches up with them!
