While honeymooning, Cassie and Sam help a new friend reconcile with her brother. Grace attempts to speed up time after a break-up. Sparks fly between Abigail and Blairsville's mayor. Martha freezes at her TV audition. Nick ghost hunts at Grey House with a friend, who's looking for more than spirits.
A mysterious, darkly beautiful woman named Cassandra Nightingale moves into an old, abandoned house which is reputed to be haunted by its original owner, "The Grey Lady". The small community is divided in their opinion of her: Some want her to stay (especially widowed police chief Jake Russell and his two children), while others want her to leave. Through the course of the story, seemingly magical things happen, and the community attributes these occurrences to her. Everyone begins to wonder if she is really a witch.
