London at the time of the War of the Spanish Succession. Queen Anne's followers are divided into two factions: one side, led by Lord Bolingbroke, is pushing for peace talks and a quick reconciliation with France; the other side, led by the influential Duchess of Marlborough, is in favor of continuing the war. Queen Anne herself is still undecided, and so a game of intrigue unfolds at court between Bolingbroke and Marlborough, each trying to win the queen over to his side.
