A young couple's 11-year-old daughter, Ivy, is repeatedly beseiged by frenzied behavior and nightmares of being burned alive inside a car. A stranger tells them that she is possessed by the soul of his daughter who died in a fiery crash minutes before Ivy was born.

A stranger comes to the quiet New England town of Castle Rock and opens up an unusual antique shop, where expensive items can be bartered for a soul. Pretty soon, the quiet little town is not so quiet.
