The villagers of Pinon drug Athos and bring him to his ancestral lands in the hopes that he will defend them against an evil baron. Athos refuses, but his fellow Musketeers come looking for him and circumstances soon force him to fight.
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.
