Synopsis by Brian J. Dillard
The second part of a crossover with Buffy the Vampire Slayer (see Buffy, "The Harsh Light of Day"), this episode of Angel guest-stars Seth Green as Oz, the werewolf rocker, and James Marsters as Spike, one of Angel's vampire nemeses. On tour with his band, Dingoes Ate My Baby, Oz comes to L.A. bearing a gift from Buffy to Angel -- the Gem of Amarra, a magical ring that makes any vampire who wears it truly invulnerable. Thinking the talisman too dangerous to use, Angel (David Boreanaz) hides it in the sewers underneath the city. Spike soon arrives and retains the services of Marcus (Kevin West), a fearsome, child-eating vampire, to torture and kidnap Angel. Although Angel keeps his mouth shut despite unimaginable agony, Doyle (Glenn Quinn) and Cordelia (Charisma Carpenter) find the ring, and, in an attempt to save their boss, inadvertently allow it to fall into Marcus' hands. Angel must chase the fiend to a crowded beach in full sunlight to prevent him for exercising his bloodlust on the amassed kiddies. Afterward, Angel uses the ring's powers to enjoy one day unharmed in the sunlight before pulverizing it to prevent it from falling into the wrong hands. Originally broadcast October 19, 1999, on the WB network, "In the Dark" marked season one, episode three of the supernatural comedy drama. It was also the first of many crossovers with the show's parent series.
