After the death of the woman who raised him and the realization that the girl he loves will never love him back, young Mark Callahan decides it's time to leave the small harbor town of Miriam's Cove for good. All that remains is one last shift at The Windcrest Hotel, a seaside resort that has seen better days.

Tonight, with a ferocious winter storm bearing down on them, there are few staff and fewer guests, until a last-minute booking takes everyone by surprise. There's a small yellow tour bus bound for The Windcrest and soon the hotel will find itself under siege by something much worse than the storm.
