Dr. Terry McBride is thrilled to come back to her hometown of Mistletoe Meadows to take over the practice of the town's retiring physician. Unfortunately, the tight housing market has her sharing a duplex with quiet and mysterious Judd Landis. Terry is unsure about the situation, since they'll share a kitchen and bathroom, but Judd turns out to be the perfect roommate, except it's obvious he's hiding something. Maybe a lot of things.

Judd wants to do the good doctor a favor, and give her a place to stay, because he knows she giving up the opportunity for a more lucrative career to come back to her hometown, but he has carefully cultivated a cover to hide the Secret Saint things he's been doing in town and he doesn't need the nosey doctor blowing his cover, no matter how kind and compassionate - and attractive - she is.

When Terry is tasked with posting on the town's social media page about the actions and possible identity of the Secret Saint, Judd is in danger of being found out. But, as they work together through the Christmas parade and a hot chocolate contest as well as helping needy members of their community, the attraction between them is undeniable. Will they see that they can do more for the community - and each other - if they pair up permanently?
