In a period of relative inactivity for the Slayer, Buffy is feeling especially put upon by the demands of her duties. She also feels her relationship with Angel is going nowhere fast. So when an older boy named Tom presents an opportunity to go to a fraternity party at the local college to Cordelia, she decides to take it.
Unfortunately, the frat worships a demon known as Machida and once a year has to sacrifice three teenage girls to it. Cordelia and Buffy turn out to be second and third (along with a girl who has gone missing from another school). They are drugged and chained to a wall - leaving it up to Giles, Willow and Xander to learn the truth and rescue them.
