In a remote corner of France lives D’Artagnan, a fearless girl with a head full of dreams and a keen sense of justice. The entire country is firmly in the grip of a narcissistic king and his power-hungry advisor, Cardinaless Richelieu. The key to their power is the mysterious golden croissant, which makes people selfish and ruthless. D’Artagnan comes up with a plan: she must become a musketeer and put an end to this nightmare! Together with the cheeky horse Holgär and the somewhat clumsy but brave Portos, she sets off on her journey.

Through epic adventures and wild confrontations, the three self-proclaimed musketeers prove that it’s worth believing in something, fighting for it, and standing up for one another.

One for all, all for one!
