Willow's trying to earn a little pocket change by taking the usual teenage part-time job - baby-sitting the neighbor's kid. But her child-care chores turn into a scene from a horror movie when the baby gives her the evil eye and attacks. Barely escaping the tiny terror, Willow can't forget the missing human child - or the monstrous thing left in its place. The childish changeling keeps coming back to haunt and taunt her.
Buffy and her posse soon discover a possible connection between Willow's infant interloper and some strange artifacts Giles found at a local archaeological dig. The evil plaguing Willow was once trapped underground. Now that it has been unearthed by new construction on the property, it's ready to cause some major mischief . . . and worse.
