When Aramis's old friend Marsac, a former musketeer, unexpectedly returns to Paris, the musketeers are thrown into turmoil, fully aware that they should report him for desertion. His appearance coincides with the royal visit of the king's beloved sister and her husband, the Duke of Savoy, whom the musketeers must protect. Marsac believes he finally knows the truth behind the infamous massacre whichhuged his troop, and wants Aramis's help to prove it. Despite their misgivings, will the musketeers help and can they prevent Marsac exacting his own revenge?.
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.
