Two teenagers – Peter Wood, an academically overachieving loner from 1985, and Charity Payne, a Puritan from 1700
Colonial Massachusetts – come into telepathic contact with each other when they have high fever from the same bacterial infection. After Peter convinces Charity she is not bedeviled, they find they enjoy each other's conversation and remain in frequent contact as they go about their day. Peter is heartened to have made at least one friend, while Charity is intrigued by the future events and technologies he tells her about. At Peter's coaxing, Charity tells her neighbors about some of her "future visions", including the
American Revolution. The notion that the
Thirteen Colonies will eventually revolt against their government is controversial, and a posse led by Squire Jonas Hacker visits Charity's home to follow up on suspicions she is a witch. When Hacker tries to examine Charity for a
witches' mark, she fears he intends to
sexually molest her and flees. Peter tells Charity to take refuge in a region less beset by panic over witchcraft, but she refuses to leave her home, so he searches library records of witch trials to see if she will be tried if she comes out of hiding. He instead stumbles on a biographical entry on Hacker, who was
posthumously convicted of a double homicide. At her trial, Charity claims that her visions come not from witchcraft, but from a God-given second sight, and uses her knowledge of the murders to
blackmail Hacker into supporting her claims. After her acquittal, Charity breaks off her relationship with Peter so that she will not risk getting into trouble again. A year later, Peter receives one last telepathic call from Charity. She has left him a message at a local landmark known as Bear Rock. Peter finds Charity's message: chiseled into Bear Rock are the initials "CP + PW" inside a
heart shape. ==Production==
