When Siobhan was just three years old, her mother died, leaving Siobhan and her father alone in their house in Dublin. They never talk about her, and now, at ten years old, Siobhan no longer remembers her mother's face.
One day, Siobhan meets a mysterious woman in the park who tells her that to remember her mother, she just needs to look in a mirror. As Siobhan grows older, she sees more and more of her mother's face in her own reflection. With time, she and her father and her own daughter are able to remember Siobhan's mother with joy and laughter instead of tears.
