What happens when there's no room at the inn and you and your potentially demonic cat become roommates with your grumpy one-night stand?

Part-time adult film actress/one-time adult film director/makeup artist Sunny Palmer has accidentally sold her very first screenplay to the Hope Channel. That was six months ago. Fast forward to a looming deadline, an uninspired Sunny has returned to the source of her inspiration in Christmas Notch, Vermont, to immerse herself in the local Christmas miracle on which her fever dream of a movie pitch was based.

Isaac Kelly, former boy band heartthrob and the saddest boy in the music biz, is the latest owner of the town's historic mansion. After his years of heartbreak following his young wife's death, Isaac's record label is done waiting for new music. What better place to attempt his first holiday album than a snow-covered mansion where he can become a hermit in peace?

But after their best friends' wedding leads to them waking up together in a freezing motel room with questionable wiring and a broken shower, Isaac takes a chance and asks Sunny to stay with him at his home. Surely the place is big enough that he'll hardly see her or her unhinged cat. But when the two discover they're both creatively blocked, they make a handshake deal: Isaac will help Sunny hunt down the truth behind the local lore, and Sunny will find Isaac a new muse.

And with these two opposites under one roof, there's no way this jingle bell mingle could go off script...right?
