It's Christmas, and Successful Magazine Editor travels from the big city to her small hometown, which is also called Christmas, to write an article on something Christmassy happening there.
Her parents' neighbour is her High School Best Friend (who got hot!) who is also single father to his Precocious Young Daughter. There's also some subplot where Precocious Young Daughter is nervous to sing a solo in her school concert which is happening on Christmas Eve, but Successful Magazine Editor helps her overcome her fear.
Precocious Young Daughter wants Successful Magazine Editor to come and see her concert, but she can't because she'll be back in the big city by then. Also Successful Magazine Editor has a fiancee in the city, who shows up just when she's starting to fall for High School Best Friend, but she ditches him at the airport when she has a change of heart and rushes back just in time to see Precocious Young Daughter sing her solo. Then Successful Magazine Editor and High School Best Friend kiss and she celebrates Christmas with them, quits her job in the big city, stays forever and they get married or something, then Precocious Young Daughter is happy because she asked Santa for a new mommy for Christmas.
There's also a tree decorating montage and a cookie baking montage somewhere in the movie.
