When Emma doesn't get the promotion she had set her sights on, she resigns. She goes home to her dad over Christmas. He runs an inn and it turns out that business is slow, and her dad is forced to sell. At the same time, Oliver is sent to finalize the deal with Emma's dad. However, he first meets Emma, and when he finally arrives at the inn, he is mistaken for a regular guest.
This is what happens when you've watched a bunch of romantic movies and try to make one yourself but haven't figured out how to do it (or simply don't have the budget needed).
