Elizabeth Is Missing is adapted from Emma Healey’s bestselling 2014 novel and stars Glenda Jackson as Maud - a woman struggling with dementia who must attempt to piece together what has happened to her best friend Elizabeth. After Elizabeth goes missing, Maud is convinced that something terrible has occurred, and she sets out to solve the mystery, all the while fighting against time as her dementia worsens. As Maud becomes more forgetful, the distinctions between past and present begin to blur - and she begins to wonder whether the mystery is connected to the decades-old unsolved disappearance of her own sister, Sukey.
