The corrupt Governor of Paris conspires with the Duke de Beaufort, primary provider of food for Paris, to stage a robbery of the city's granary and pin it on the refugees, only to later sell the stolen grain back to the King at an inflated price. D'Artagnan is taken captive along with the rioting refugees, and the other Musketeers (along with D'Artagnan's wife Constance, now in charge of the Musketeer garrison) must rescue them from the hands of the Red Guard before they are executed.
Set on the streets of 17th-century Paris where law and order is more an idea than reality, the series follows Musketeers Athos, Aramis and Porthos who are far more than King Louis XIII's personal bodyguards, but ultimately stand resolutely for social justice: for honour, for valour, for love and for the thrill of it.
