Lena and Martin were once madly in love. But, like many marriages, time and circumstance eventually took their toll, and they decide that everyone's lives would be better if they got a divorce. Facing a daunting real estate market, the couple decide ... (more)not to sell their house and to "Bird Nest" instead. The 'on-duty' parent will live in the house while the 'off-duty' parent will live in the detached garage. As Lena begins to dip her toes into the dating waters, Martin begins to see his own culpability in his marriage falling apart.
