Historian Tracy Borman reconstructs the days leading to Anne Boleyn's arrest in the spring of 1536, working almost hour by hour through the collapse of Henry VIII's second marriage. She walks the grounds of Greenwich Palace and the Tower of London, laying out how a queen who could no longer produce a male heir became vulnerable to the ambitions of Thomas Cromwell and rivals at court. The episode weighs the accusations against her, adultery, incest with her brother George, and treason, against the alternative reading that she was engineered out of the way by a political coup. Original documents and Anne's own last letter to Henry anchor the case, alongside the confession extracted from court musician Mark Smeaton that implicated the men eventually tried alongside her. Rather than settling the guilt question outright, the film lays out the evidence and the competing motives at court, leaving the viewer to judge whether Anne conspired against her husband or was simply no longer useful to him. It is the first of a three-part series.
