In his home village near Tarbes, the young D'Artacan dreams of being an expert swordsman and a member of the famous Muskehounds.

On his journey to Paris, D'Artacan is insulted by a man with a black moustache, who then gallops off. The man, subsequently, returns to rob D'Artacan of his letter of introduction.

D'Artacan is unable to get to see M. de Treville without his letter of introduction. Penniless, he has to sleep in the street.

A double of Pontos is seen robbing ladies in the street. However, the real Pontos is shown innocent when his friend Amis produces the double, who is promptly shot by Widimer.

D'Artacan sees Dogos and Amis duelling with a group of Guards. Widimer appears and tries to arrest them as duelling is illegal.

D'Artacan manages to offend each of the Three Muskehounds in turn. He has to fight a duel against each of them, but the first duel is broken up by Widimer and the guards.
