London, 1955. The Leader has been dead for two years. His assassination, on British soil, provoked violent retribution and intensified repression of British citizens, particularly women. A government propaganda drive to promote positive images of women has just been announced ahead of a visit from Dwight D. Eisenhower, the first American president to set foot on English soil in two decades. Queen Wallis Simpson will be spearheading the campaign, and Rose Ransom has been tasked with visiting her to explain the plan. When Rose arrives at the palace, she finds Wallis in a state of paranoia, desperate to return to America and enjoy the liberty of her homeland following her husband's death. Wallis claims she has a secret document so explosive that it will blow the Protectorate apart. But will the last queen of England pull the trigger on the Alliance?
