Living as she was with encroaching dementia, widowed grandmother Maud Horsham (Glenda Jackson, returning after a 27-year screen hiatus) found no acceptance of her concerns after her best friend Elizabeth (Maggie Steed) failed to make a promised visit. As she tries to piece together the truth, she's haunted by her far clearer recall regarding the disappearance of her sister Sukey (Sophie Rundle) 70 years earlier. Acclaimed take on the Emma Healey novel co-stars LIV Hill, Nell Williams. 87 min. Widescreen; Soundtrack: English.
