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.
