Erin has always supported her husband Adam, a heart surgeon, by organizing the hospitals' Christmas charity galas. However, when he moves to a new hospital, her help is no longer needed. Feeling lost and without a purpose back in New York City, her long-suppressed regrets over giving up her dream of pursuing fashion design start bubbling up. When Erin is given a peculiar heart-shaped Christmas ornament, she wakes up in an alternate reality where she's a world-famous fashion designer. As she "meets" and attends Christmas events with alternate-universe Adam, she realizes that while her fashion dreams came true, it's lonely at the top. While working on a way to bring more charity and heart to her fashion empire, she learns that her dream life and love were always right in front of her – if only she finds the heart and courage to ask.
