The series is set in Medieval Europe, and mainly concerns the adventures of Johan, a young squire and his jester sidekick Peewit, and includes elements of sword-and-sorcery.

Set in the Middle Ages in an unnamed European kingdom, the series follows the adventures of Johan, a brave young page to the King, and Peewit, his faithful, if boastful and cheating, midget sidekick.

Johan rides off in search of adventure with his trusty horse Bayard, while Peewit gallops sporadically, and grudgingly, behind on his goat, Biquette.

Struggles for power between deposed lords and usurping villains form the basis of many of the plots which also contain elements of detective fiction as the pair hunt down traitors and outlaws, as well as fantasy, with witches and sorcerers, giants, ghosts and, above all, the Smurfs.

Peewit acquires a flute, which is bad enough for the castle's inhabitants, but this one has the ability of making its audience dance crazily before they collapse from exhaustion.

When a thief steals it and uses it to commit further robberies, Johan and Peewit decide to consult the flute's makers: some little blue beings called the Smurfs.
