Lena decides to call Martin's bluff on selling the house but is surprised when he actually begins making necessary repairs to get the house ready to be sold. The realtor sends over a contractor to deal with the structural issues she discovered in the house. Meanwhile, upset that Mae is not enjoying her sophomore year of high school, Lena invites Emma-Rebecca, Mae's friend from camp, to visit; yet she seemingly brings a trail of bizarre and supernatural events along with her.
A newly divorced couple embrace the unconventional as they co-parent their children by trading residences each week, alternating between one living in the main house and the other in the garage apartment as they also adjust to being single for the first time in years. This new arrangement will land Lena and Martin in some precarious situations, with Lena's doting sensibilities and Type-A personality clashing with Martin's laid-back temperament as they attempt to raise the kids separately but together. What will Lena and Martin do with their unfamiliar moments of freedom? And how will they manage their feelings when this freedom is met with the nostalgia for what they once shared as a couple and their mutual longing for their family to be whole again? With the help of friends Arthur and Camille, plus Lena's sister, Maya, this former couple will explore what it means to live apart... under the same roof.
