Hamish Kenneally is moving from Australia to the US for a fresh start, beginning with Christmas at his sister's place in Idaho. When a snowstorm diverts his plane to Montana and leaves him stranded two days before Christmas, he hires a car and drives right into a blizzard.

Ren Brooks has always called Hartbridge, Montana, and his family hardware store, home. After a few failed attempts at love, he's resigned to being single forever—after all, no guy wants to stay in his sleepy little town for long. And after his dad's passing earlier in the year, Ren's Christmas is looking bleak. But when a car runs off the road in front of his property, Ren pulls the driver out and takes him home to get out of the cold.

With the storm and the holidays leaving Hamish with nowhere else to go, Ren kindly offers a place to stay. Hamish is certain he's crashed right into a Hallmark Christmas movie, despite more car delays and road closures and the prospect of not seeing his sister for Christmas. And with help from Hamish, Ren is beginning to feel a little Christmas cheer.

These two unlikely strangers have more in common than they first realise, and after two days of Christmas decorations, cookies, and non-stop conversation, it looks like Christmas might be saved after all.
