When a night of champagne-fueled recklessness and newfound confidence lead Kate Crosby to single night of passion with big-time businessman — and her archenemy — Peter Logan, she is certain that it will never become anything more. Of course, she didn't count on their covert hookup making the front page of the tabloids — nor could she have guessed that she would end up secretly pregnant with his baby. So, Katie escapes to her family's remote Wyoming ranch, hoping the whole ordeal will blow over and Peter will never find her.

But Peter refuses to accept her silence when he learns the truth about her identity. When he shows up at her cozy hideaway, it's just in time for a blizzard to snow them both in, forcing Peter to stay. When he discovers Katie's secret and learns that he'll be a father for the first time, Peter realises this new family is more important to him than any business transaction — but he'll have to convince Katie his love is forever first, and he'll have to do it before the plows reach the isolated mountain hideaway and Kate leaves for good.
