Josh and Cornelia Srebnick are happily married middle-aged members of New York's creative class. They tried to start a family and were unable to - and have decided they're okay with that. But as Josh labors over the umpteenth edit of his cerebral new film, it's plain that he has hit a dry patch and that something is still missing. Enter Jamie and Darby, a free-spirited young couple, who are spontaneous and untethered, ready to drop everything in pursuit of their next passion - retro board games one day, acquiring a pet chicken the next. For Josh, it's as if a door has opened back to his youth - or a youth he wishes he once had. It's not long before the restless forty-somethings throw aside friends their own age to trail these hipsters who seem so plugged in, so uninhibited, so Brooklyn cool. But is this new inspiration enough to sustain a collaboration and friendship with a couple twenty years their junior?
