A group of half-breed demons come to Angel for help. They learn that a racist group of demons,The Scourge, are in town and are out for impure demon blood.
Angel attempts to secure safe passage to a demon-friendly island for the group and discovers the Scourge plan to eliminate the half-demon breed population with a machine whose rays can wipe out any human within a quarter mile radius.
Angel and Doyle argue over who should disarm the device, with certain death the reward. Angel and Doyle realise that one of them will have to die in order to disconnect the beams. Doyle knocks Angel out, kisses Cordy and makes the ultimate sacrifice.
