The young D'Artagnan arrives in Paris with the ambition of joining the king's Musketeers of the Guard. There he befriends three musketeers, Athos, Porthos and Aramis, and together they get mixed up in various adventures, ranging from fighting with the guards of the scheming cardinal to getting involved in the love intrigues of the queen with the Duke of Buckingham. From their trips to London for the affairs of the queen to the siege of La Rochelle with the army of the king, the four friends remain inseparable, taking as their motto "One for all and all for one." This new adaptation of the most widely read work of Alexandre Dumas (the father) for children and young audiences simplifies the plot of the original, while retaining the vitality of the dialogues of the author. The addition of songs emphasizes the timeless messages of the play, while the motto "One for all and all for one", at a time when childhood violence is on the rise, invites children to become in their turn young musketeers in their schools and neighbourhoods.
