Scientist Cassandra Reilly undertakes an experiment to time travel to Jane Austen's England. There, she finds unexpected love, and is plunged into a frightening adventure.
Dr. Cassandra Reilly, a scientist from the year 2120, embarks upon a time travel journey to England of 1820. Her purpose: to conduct an experiment, living in the time and place where her idol, Jane Austen, lived. Though she has painstakingly prepared for the experience, her neighbors in the County of Hampshire sense something strange about her. Her beauty attracts a handsome violinist, and they begin an affair, endangering her reputation in the community.
Just when Cassandra has settled in to her new life, her grown son, James, suddenly arrives on her doorstep, popping in from the future. James becomes a popular addition to Hampshire society, but he makes a terrible mistake. He brings with him a device from the future and shows it to a young friend. She is terrified by its inexplicable properties and creates a public scene. Cassandra’s enemies get the authorities involved in an investigation of the "dangerous" device. James is arrested and it is up to his mother to free him from a London prison and return him to the future. But help comes from a surprising source, and ultimately Cassandra realizes that love is not always what it seems to be.
