As the holidays approach, Emily and Jared are looking forward to celebrating the holidays together again, this time as a couple. Emily, now embracing Evergreen Lane's uniquely festive spirit, is ready to work with Jared, Ned, Mary Louise and Pamela to make this year's Christmas celebrations the best yet – even if being the HOA president's girlfriend doesn't stop those dreaded decorating citations.

When the soon-to-be neighbors turn out to be holiday royalty, it looks like this year's competition is about to heat up. As the welcoming committee prepares for the new arrivals, only one thing is certain – this Christmas, Evergreen Lane is going to sleigh!
