For Karina, it's the chance of a lifetime: a free cocoa and gingerbread-filled holiday at a quaint Michigan B&B called The Christmas House. In return, Karina will play spy and report back to the company hoping to buy out the popular hotel. It's all too good to be true, especially when Karina meets innkeeper Reid Sullivan. The man is a walking talking Christmas miracle—and she's hoping to meet him under the mistletoe. Single dad turned globe-trotting adventurer, Reid isn't quite sure how he and his daughters got roped into helping out this year at his family's B&B. But once he arrives, it doesn't take long for a certain guest to catch his eye. Fun-loving California girl Karina is hard to miss, and Reid senses the attraction is mutual. As Christmas approaches and the weather grows colder, things between Reid and Karina heat up. But when the true reason behind Karina's visit is revealed, will the holiday magic disappear before the ball drops on New Year's Eve?
