Christmas, her favorite time of year, is only seven weeks away, and her boyfriend has just popped the question. David is steady and reliable, and Holly knows he'll give her a wonderful life. The kind of life she's always wanted.

Then her new neighbor moves in.

Josh O'Toole is also approaching the festive season with joy. He loves his teaching job. He's about to have a baby with his adored girlfriend, Stephanie, and they've just moved into a new home to begin their life as a family.

But as Josh and Stephanie settle into their new house across the road from Holly and David's, things begin to get complicated and soon the Christmas gifts aren't the only things that have to be kept under wrap this holiday season.
