It’s a Wonderful Life meets Groundhog Day, as a woman dangerously close to losing it all receives an unexpected Christmas gift that prompts a surprising journey of self-discovery... and another chance at happiness.

What if you could have one more day with someone you lost?

Diana Merriman, a physical therapist, is probably the only person in the small town of Snow Haven, North Carolina, who isn’t looking forward to Christmas. It’s been three weeks since her fiancé Linus was critically injured when a car hit him as he biked home from the toy store he owns and manages. Watching him open his eyes is the only gift she wants, but she can’t help losing a little more hope every day.

But an unexpected visit from a friendly neighbor and finding a snow globe of Snow Haven—a gift Linus had hidden in the closet—the night before Christmas Eve changes things in ways Diana never would have imagined. Because on Christmas Eve Diana wakes up to find that it’s not—Christmas Eve, that is. Instead, it’s somehow December 4 all over again, the day Linus got hurt, and as mystified as Diana is, she immediately starts a plan to save her partner from his fate.
