After a week hiatus The Musketeers return to investigate Emilie of Duras (Emma Lowndes), a woman claiming to have visions from God which instruct her to lead her thousands of followers into war with Spain.

As word of Emilie’s visions trigger violent anti-Spanish riots, Aramis is sent to discredit her before she pushes France into an ill-timed war with Spain.

Meanwhile Rochefort continues to clash with Spanish Ambassador Perales. He resorts to blackmail and murder to resolve the problem.
