Recipe for an intense holiday romance: Take one desperate 19th century Highlander. Combine with a determined young woman from the 21st century who wears underwear for a hat. Over low heat, add a haunting tune... As wicked weather isolates the pair within the frozen walls of a Scottish castle, they’ll need to learn to trust each other. If they can’t come together to solve a disturbing mystery, they’ll have more to lose than their hearts. And more to rue than just a Christmas kiss.
