Vincent and Penelope have been unsuccessfully trying to have a baby for years; and Kit and Diana are bound up in a cycle of miscommunication and disconnectedness. The four suddenly find themselves embroiled in a sexual revolution. Together. But an unexpected pregnancy threatens to tear the foursome apart. Is this the end of what could have been a beautiful relationship?
