Alone during the holidays, Christmas enthusiast Brittany Adams leaves her sun-drenched beach town to help her injured cousin in the Great Smoky Mountains. But she finds herself thrown into the heart of small-town Christmas dynamics. Tasked with saving her cousin's failing home tour, she decides to convince charmingly grumpy Chris Hart to open his historic Amelia House for the tour.

But Chris, haunted by painful Christmas memories, has sworn off holiday festivities. Undeterred, Brittany sets out to win him over by pledging to ready his home if he agrees to participate. As they work together, chemistry ignites, but their budding romance is threatened by the secrets of Chris's past. With the help of a stray dog named Bo and the warmth of mountain-town hospitality, can Chris find the true meaning of Christmas before Brittany leaves for good?
