France, in the late
Middle Ages. King Gros Pif () is an incompetent, lazy and gluttonous monarch, who neglects his duties while the tax-collecting
musketeers oppress the people. The
Queen consort, in league with several court members - including the
jester who is also her lover - stages a
coup and dethrones Gros Pif. Only the King's cousin, well-meaning but goofy Princess Lucienne, remains loyal to him. The conspirators eventually prove even worse rulers than Gros Pif. The White Knight, a handsome and gallant, if dim-witted, swashbuckling hero, intervenes and helps Lucienne free Gros Pif from his cell. All three escape from the castle and endeavor to thwart the usurpers and restore Gros Pif to his rightful, if undeserved, throne. As a
running gag, the film includes musical interludes which consist of the White Knight repeatedly breaking into an impromptu
operetta-style
theme song about himself, much to the King's annoyance. ==Cast==
