Responsibility, isolation, and loneliness. On the Scottish downs, in a solitary farmhouse, Louise cares for her mother, Daisy, a woman whose dementia is getting worse. On the day before Daisy’s birthday, Louise finds her wandering on the downs. The next morning, the postman delivers flowers but declines an invitation for a cup of tea. While Louise is talking on the telephone to her sister, who has phoned to say she’s not coming for the birthday, Daisy wanders out again. This time Louise finds her standing knee-deep in a swift cold stream. Louise gets her Daisy back to the house and into the bath to warm up. Is this too much to handle?
