距离圣诞节还有一周，美丽的蒙特纳罗女公爵玛格丽特与长相跟自己一模一样的芝加哥平民史黛西对换了身份。在圣诞老人助手的魔法下，玛格丽特爱上了史黛西英俊的同事，而史黛西则爱上了玛格丽特的未婚夫，一位风度翩翩的王子。One week before Christmas, Margaret, the gorgeous Duchess of Montenaro, switches places with Stacy, a "commoner" from Chicago, who looks exactly like her. With the assistance of a magical Santa's helper, Margaret falls in love with Stacy's handsome co-worker, while Stacy falls in love with Margaret's fiance, the dashing Prince.
