It’s 1848 and preparations are underway for Annie Gibson’s wedding to Bilsden’s wealthy mill-owner, Frederick Hallam. But not everyone is pleased by the event. Frederick’s daughter, Beatrice, is horrified at the prospect of a new and attractive stepmother arriving at the house on Ridge Hill. Even Annie’s own family feels threatened.
Soon, however, real troubles begin to pile up for the Gibsons. Annie’s brother, Tom finds that he is father to a child he knew nothing about. Annie’s son, William, is devastated to discover out that his real father is not the man who brought him up. And even Annie’s joy cannot last because someone has uncovered the secrets she has fought so hard to keep hidden.
