Salem, Massachusetts, 1692. In a plain meetinghouse, a woman stands before her judges. The accusers, girls and young women, are fervent, overexcited, just on the edge of breaking out into convulsions. The accused is a poor, unpopular woman who had her first child before she was married. As the trial proceeds, the girls begin to wail, tear their clothing, and scream that the woman is hurting them. Some of them expose wounds to the horrified onlookers, holding out the pins that have stabbed them -- pins that have appeared as if by magic. Are the girls acting, or are they really tormented by an unseen evil? Whatever the cause, the nightmare in Salem has begun.
