Both ABC Entertainment and Facebook announced a partnership to stream the first episode of the new comedy series on the show’s official Facebook page.

In the episode, Maya DiMeo moves her family to a new, upscale school district where she finds the perfect situation for her eldest son, JJ, who has cerebral palsy. While JJ and his sister, Dylan, are thrilled with the move, middle son Ray is frustrated by the family’s tendencies to constantly move, since he feels his needs are second to JJ. Soon, Maya realizes it is not the right situation for JJ and attempts to uproot the family again. But JJ connects with Kenneth, the school’s groundskeeper, and asks him to step in as his caregiver, and Ray manages to convince Maya to give the school another chance.
