The Christmas Queens of North Pole, Vermont, Trish and Diana, have won the Best Holiday House decorating competition every year for the past nine years. But days before Christmas, a friendship-ending argument sparks a town-wide feud and draws the attention of a national magazine writer hoping to make a name for herself with her scintillating expose.

Chelsea is an American visiting England for work. While inspecting an old estate for its real estate potential, she notices some strange lights in the cellar. She discovers a "portal" of sorts that shows her the past (end of 1700s) and the dashing owner of the old estate. When an accident occurs, the gentleman (Charles) comes through and gets stuck in the present day.
