Emily tells her son Paul, now six years old, the story of his life - how she sought motherhood, to be a mom without a husband, to raise a perfect, exceptional child, whom she calls Loverboy. In flashbacks told around a pretend car trip they take - so he can practice driving - we see Paul's infancy, their fun together (sometimes with a manic edge), and his growing desire to go to school and be with other kids. We also flash back to Emily's childhood, with parents so bound up with each other that she's virtually ignored. Is Emily going to be able to let Paul be with others? Or, can she, as in the David Bowie song she sings at a school talent show, construct a life on Mars?
