Vlad, the new contractor for the house, arrives with his crew and Lena immediately begins to clash with him over his methods of repairing the house. Martin, on the other hand, feels that Lena should let them do what they were hired to do. After overhearing that she's too uptight, Lena calls up an old friend to help her let out her frustrations. Elsewhere, Martin takes Mason camping to help him get over his breakup with Hazel and to teach him how to be a man, only to learn from him that it is okay to express his emotions.
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.
