What is What If Christmas about?

Here’s the synopsis from Hallmark Channel:

“Erin (Loughlin) has always supported her heart surgeon husband, Adam’s (Cavanagh) career 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.”
