Roberto Ridolfi leaves England to coordinate a Spanish invasion of England with the Duke of Alva, the Pope and Philip II. This plans to rescue Mary Queen of Scots, depose Elizabeth I and restore Catholicism. However, Alva, busy with his own challenges in the Netherlands, refuses to support such a plot unless it is begun by a successful rising of English rebels.
