It has been 20 years since the musketeers thwarted Richelieu’s schemes against the Queen. Now France has “troubled times.” Feud between the Parliament and the royal court, noble uprisings against the new cardinal—Mazarin. Four friends are again destined to meet in order to serve their country, but this time they end up “on opposite sides of the barricades.” Yet the motto of their youth—“One for all, and all for one!”—prevails over political preferences, and the inseparable quartet together tries to save the noble and unfortunate King Charles I from execution.
