Als Dank für ihre tapferen Taten erhalten D’Artagnan und seine Freunde den ehrenvollen Auftrag, die Juwelen dem spanischen König zurückzugeben, als ein Zeichen der Freundschaft zwischen beiden Ländern. Kardinal Richelieu gefällt diese Entscheidung gar nicht. Seine Männer erpressen Marco, eine spanische Zirkusmaus. Sie soll ihnen helfen, D’Artagnan und die drei Musketiere in das Gefängnis in den Kellern von Notre Dame zu bringen.
The King decides to give the jewels to the King of Spain, their original owner, as a goodwill gesture. Dogtanian and the Three Muskehounds are chosen to deliver them, to Richelieu's annoyance. The circus is in town, and the star turn is Marco the mouse with his impression of the Cardinal. His guards break up the show and arrest Marco. Richelieu tricks him into working against the Musketeers. Marco visits Pip, who defended him at the circus, and persuades him and his friends to help look for Marco's missing father. Richelieu's men imprison Pip in the cathedral of Notre Dame and Dogtanian and the others in a disused church. With the Muskehounds out of the way, the Cardinal's men will be chosen for the mission. But when Marco collects his reward he realises that he has been duped and returns to rescue his friends.
