Jules Daly is an antique store worker in Buffalo, New York, who becomes the legal guardian of her niece Maddie and nephew Milo after the loss of her sister and brother-in-law.

Paisley Winterbottom, the butler of the children's wealthy grandfather, Duke Edward appears with an invitation for Milo and Maddie to spend the Christmas holidays with his employer in the country of Castlebury.

Jules initially refuses, but decides to go for the children's sake when Paisley claims that the Duke is ill.

Arriving at the palace where the Duke is in good health, Jules meets Prince Ashton, the brother of her sister's husband Charles and falls in love with him.

Finally appreciating the spirit of the season, he tells Paisley to send invitations out for a Christmas Eve ball.

Overhearing Ashton and Edward speaking disapprovingly of someone "untitled" and "crass" they'd rather not invite to the ball, Jules mistakenly believes it to be about her, though they are actually talking about someone else.

In August 2008, writer and director Michael Damian told OK Magazine that he was "working on a screenplay called Christmas At Castlebury Hall".
