After failing to inoculate Connor (Vincent Kartheiser) against the profane influence of Jasmine (Gina Torres), Angel (David Boreanaz) beats the boy senseless and stages a daring escape from the hotel. Fred (Amy Acker) feels just sick about leaving Connor and the comatose Cordelia (Charisma Carpenter) behind, but Angel advises her and the others to deaden their hearts if they want to survive. Taking to the sewers, the fang gang soon encounter a group of feral teen demon-hunters. Skulking underground ever since The Beast extinguished the sun (see "Long Day's Journey"), the kids have escaped Jasmine's influence, but are being picked off slowly by an unseen creature. Wesley (Alexis Denisof) soon encounters the skittery, spider-like creature (Jeff Ricketts) and learns that it's part of an ancient, otherdimensional demon race who have worshipped Jasmine for millennia. Held prisoner as the demon performs a blood ritual in Jasmine's honor, Wes ferrets out some intriguing information about the sinister higher being. Meanwhile, Jasmine herself continues "eating" her followers, including Cordelia -- or so it seems. Connor isn't too happy about this turn of events, but Jasmine uses it to draw him even closer. She also manages to seize control of one of the sewer-dwelling teens, who leads Connor and an army of followers straight to Angel, who is in the process of rescuing Wes from the spider-demon. Surrounded and outnumbered, the gang steel themselves for one last stand -- until Wes opens a portal to the spider-demon's home dimension. Determined that at least one person survive to fight Jasmine another day, Angel crosses through -- and into a hellish landscape full of countless additional skittering demons. Originally broadcast April 23, 2003, on the WB network, "Sacrifice" marked season four, episode 20 of the supernatural soap opera.
