On the evening of February 13th 2021, 65-year-old retired accountant Penny Jackson argued with her husband David over which potatoes should be served with dinner. Hours later, Penny stabbed David to death. When recordings of Penny’s callous reactions that night were later publicised, Penny became a viral internet sensation and her trial became global headline news – as a jury asked: what could have led this seemingly respectable, middle-class woman to such violence? In this intimate 90-minute documentary, Penny and David’s closest friends and family speak out about the realities behind the headlines, and the hidden tensions behind this ostensibly everyday marriage.
