The films climactic sequence is a series of arrests and killings of anti-Elizabeth conspirators intercut with the queen praying, a straight lift from (or tribute to, depending on your point of view) the climax of Godfather. According to the film, the conspirators were the Dukes of Norfolk, Sussex and Arundel, with help from Spain, Mary of Guise, the French-born mother of Mary Queen of Scots, the Pope, and, of all people, Robert Dudley! The plot involved overthrowing Elizabeth and replacing her with Mary Queen of Scots, who Norfolk would marry. In the film, Walsingham gets to know of the plot, arrests the Dukes in time, and kills Mary of Guise and the Spanish ambassador to England. The Dukes are executed, but Elizabeth pardons Dudley, thus condemning him to a life of endless guilt. The whole thing appears to have taken place in 1562 or 63.
