Lena and Martin were once madly in love. But, like many marriages, time and circumstance eventually took their toll and the romance disappeared. Lena, the perfectionist, fell into the role of caretaker for everyone, including Martin. Martin felt he could never do anything right and gave up making the effort. Finding themselves in a platonic marriage and acting more like a pair of camp counselors wrangling their kids than a couple hopelessly in love, they decide that everyone's lives would be better served if they got a divorce.
Still wanting the best for their three kids and facing a daunting real estate market, the couple decides to "Bird Nest" instead. One parent will live in the house as the "on-duty" parent taking care of the kids, while the "off-duty" parent will live in the detached garage, doing whatever he or she pleases while switching off every other week. Could being apart ultimately lead to them getting back together?
In the premiere episode, after breaking the news to their friends and family about their divorce, Lena has to deal with her son Mason's growing pains. Meanwhile, Martin, still feeling guilty about refusing to dance with Lena at their wedding, secretly tries to atone for his oversight and surprise his ex-wife with new moves.
