Mazarin hires D'Artagnan to find the other musketeers in 1649: Mazarin fears an insurrection, especially from the popular Beaufort. A bored abbé and a brawler raising an intelligent son help Beaufort in secret. Mazarin uses the musketeers to liberate Charles I after they failed to stop Beaufort's prison break. Milady de Winter's vengeful daughter Justine is also after them. It's a race against time to save Beauford's political reforms and escape England.
