During a visit to Trieste in Northern Italy to research his long lost great-grandfather, Jacob meets Charlotte and Jane, and the three are forced to confront their individual and shared histories. Their sense of themselves is challenged and they must piece together a future none of them saw coming. A Perfect Mother asks big questions: What do we inherit from the broken histories of our parents and our grandparents and how does this shape our own sense of identity? Can we ever escape the past? Are stories, the ones we are told and the ones we tell, integral to how we know each other and how we love? What does it mean to be a good parent, let alone the perfect mother?
