In a sweet little town, there is a very particular three-story house that is the center of the town's annual Halloween celebration. Each year, the mysterious couple that lives there transforms their wrap-around porch into something new and fantastical and wows the entire town. The neighbors talk about it all year long! This year, however, it is an 8-year-old girl named Margaret that does something at once surprising and gracious which changes the town's Halloween tradition forever.
