87-year-old Greek immigrant Koula Agiostratitis recounts how her husband Theo’s dementia diagnosis affected their six-decade-long marriage. Through Koula and her daughters, Vivian and Phyllis, we witness how their once music-filled home is transformed by what the family describes as “the longest goodbye.” This intimate portrait of love, caregiving and cultural duty reflects on how memory loss reverberates beyond the individual to reshape the fabric of family and culture.
