A merrybegot and minister's daughter -- two girls who could not have less in common. Yet their fates collide when Grace and her younger sister, Patience, are suddenly spitting pins, struck with fits, and speaking in fevered tongues. The minister is convinced his daughters are the victims of witchcraft. And all signs point to Nell as the source of the trouble....
