Buffy the Vampire Slayer

Picking the wrong night for mother-daughter bonding, Joyce discovers the bodies of two children in the park, apparently sacrificed in an occult ritual. Deeply disturbed by what she has seen, Joyce rallies the adults of Sunnydale, convincing them to rid the town of all magical and occult influences. Soon, however, it becomes apparent that Buffy, Willow, and Amy are themselves considered a part of the occult threat to Sunnydale.
