On-set veterinarian Goldie MacKenzie (Cahill) leaves the glamour of Hollywood behind to buy a family-run veterinary clinic in tight-knit Blue Dog Valley, arriving just in time for the town's cherished Christmas season. When Dr. Gable, the clinic's longtime owner, unexpectedly ends up out of town, Goldie is hosted by his handsome son Cohen (Walker), the black sheep of the family because he decided to forego their expectation of becoming a vet. Cohen and Goldie get off on the wrong foot, but when the folks of Blue Dog Valley cold shoulder "the newcomer," Cohen teams up with Goldie to win over even the frostiest of community members. Goldie is also aided by the mysterious canine she dubs Blue whose spontaneous appearances always seem to guide Goldie to exactly where she needs to be. As Goldie works hard to prove herself to the townspeople when furry and Christmas crises arise, she finds herself pulled towards the very heart of her new-found home... and a certain black sheep.
