Will Ferrell and Kristen Wiig, financial book author Robert and organic goods seller Sarah, play a married couple who are still licking their wounds years after Sarah while pregnant with their only child due to a calamitous accident on the dock of the lake just outside their property. After Sarah is revealed to be unable to bear any more children, the couple decide to the adoption agency route, eventually bringing into their home single-and-unready twenty-something mom-to-be Bridgette, six months pregnant and willing to give them an addition to their family. However, Bridgette has some ulterior motives, including a fatal attraction to Robert, whose ability to be close to Sarah has been wavering since the accident.
