An elderly Marjorie's memory is fragmenting. But she has a new companion: handsome, programmed to know her past perfectly. Memory, however, is never quite what we think it was.
Marjorie is old and her memory is going. To keep her company, she has a Prime: an artificial intelligence that takes the form of her late husband Walter, though young now, the way he was decades ago. Fed details from the family's recollections, he sits with her and tells her the stories of her own life.
