Spanning from 1980s London to a present-day reality TV show, A House Full of Windsor explores how one woman’s messy past shapes her family’s future and how long-buried secrets and resentment must come to the surface for them to move on. Debbie Windsor was always fascinated by royalty, but when her marriage fell apart, she turned to collecting to fill the void. Now the house is a royal mess, and Debbie’s health and safety is on the line. Even her etiquette-expert daughter can’t fix this disaster, and when the entire family ends up on a hoarding show, everyone has something at stake.
