After a wizard's spell goes awry, 12th-century Gallic knight Godefroy de Papincourt, Count of Montmirail finds himself transported to 1993, along with his dimwitted servant, Jacquouille la Fripouille. Startled and perplexed by modern technology, the duo run amok, destroying cars and causing chaos until they meet Beatrice de Montmirail, an aristocratic descendant of the nobleman, who may be able to help them get back to 1123.
Raised by his science teacher father, Joseph Pagnol, and seamstress mother Augustine, young Marcel grows up during the turn of the century in awe of his rationalist dad. When the family takes a summer vacation in the countryside, Marcel becomes friends with Lili, who teaches him about rural life.
To his chagrin, young Marcel Pagnol and his family move back to their home in Marseilles, France, far from their pastoral holiday cottage in the hills. Determined, Marcel makes the long voyage back to the cottage on foot and lands himself in trouble. One day Marcel's father discovers a shortcut to the cottage, but it requires trespassing. Despite their trepidations, Marcel and his family begin using the secret trail to reach their cottage.
