In the snowy perfection of Aspen, the White family gathers for youngest daughter Rosie's whirlwind Christmas wedding. First to arrive are the bride's parents, Maggie and Nick. Their daughter's marriage is a milestone they are determined to celebrate wholeheartedly, but they are hiding a huge secret about their own: they are on the brink of divorce. After living apart for the last six months, the last thing they need is to be trapped together in an irresistibly romantic winter wonderland. Rosie's older sister Katie is also dreading the wedding. Worried that impulsive, sweet-hearted Rosie is making a mistake, Katie is determined to save her sister from herself. If only the irritatingly good-looking best man, Jordan, would stop interfering with her plans... Bride-to-be Rosie loves her fiance but is having serious second thoughts. Except everyone has arrived - how can she tell them she's not sure? As the big day gets closer, and emotions run even higher, this is one White family Christmas none of them will ever forget.
