As Catesby and his men load 6,000 pounds of gunpowder into a secret cellar underneath Parliament, Father Garnet is visited by the Constable of Castile, who pressures him to reveal details of Catesby's plot.
An unwitting revelation allows the King to catch wind of the plan, with Lord Cecil tasked to root out the conspirators. Anne implores Catesby to flee the country for the sake of his young son, as Cecil and his henchmen close in.
