Returning from Brazil with his wife and daughter, Oisìn is looking to rebuild a life in Ireland and reconnect with his mother, Brigid, who has early onset Alzheimer's. As her condition deteriorates she starts to speak Irish, the language of her youth, and reflect on her childhood dreams and aspirations. Mother and son embark on a journey of personal discovery, and as past traumas are exposed they begin to understand what has shaped them and who they really are. The Language of Remembering asks how we connect to the people we love and how we move on from the past to find meaning in the present.
