Renowned astronomer Marmion gathers the Royal household to his impressive observatory in a transformed old fort to watch a solar eclipse. Rochefort along with The Musketeers escort them but could never have predicted the twist in fate that ensues and the impossible choices that must be made. Who is Marmion really and what is his game? The Musketeers are forced into the fight of their lives with dramatic consequences. Will they accept Milady's help despite their loathing and mistrust of her? It might be their only chance to save the King, Queen and themselves.
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.
