Plot Synopsis

Liz has everything a girl could ever want -- a successful career as a doctor and an equally successful fiance who can't wait to marry her. Yet somehow, things just aren't clicking for Liz as she can't help but remember some past relationships that ultimately let her down. And when she runs into Sean, a dear old friend, at a Christmas party, an impulsive moment under the mistletoe confuses her further. Lucky for her, her guardian angel, Tom, gives her the rare opportunity to find out exactly how a single choice can change a life. He quickly travels back in time to recruit a younger Liz and then forward in time to find Liz as the more mature Beth only to return to steer present-day Liz from making a big mistake. With guidance from spirits of past and future, Liz suddenly realizes that she might be marrying the wrong man and must make up for past mistakes in time to secure her future with a lifelong love.
