It also features Marie-Anne Chazel, Christian Bujeau, Isabelle Nanty and Didier Pain in supporting roles.

In the film, a 12th-century knight and his squire travel in time to the end of the 20th century and find themselves adrift in modern society.

The publicity for the film used the tagline Ils ne sont pas nés d'hier ("They weren't born yesterday").

One of his vassals, Count Godefroy de Montmirail, nicknamed "the Bold", guards their meeting place.

Having to flee from incoming enemy troops, Louis VI finds himself faced with an English soldier who seeks to capture him.

Frénégonde is informed of the arrival of Godefroy and runs out of the castle to join him, pursued by her father who tries to restrain her eagerness.

While the occupants of the castle gather in a chapel near the remains of the Duke, Frénégonde takes an oath to retire to a convent for the rest of her life: she says she cannot marry the man who killed her father.

Jacquouille, who was busy keeping the flies away from the dead body, takes advantage of everyone else's departure to steal the Duke's heavy gold necklace, set with precious stones.

Godefroy travels to the mage Eusæbius, a man versed in the magic of time, in order to repair his mistake and ensure he can create a lasting lineage with Frénégonde.

The mage then realizes that he has forgotten the quail eggs in the potion, an essential ingredient, and declares in alarm that "it's a catastrophe".

A Renault 4 car belonging to the French postal service arrives and brakes suddenly in front of Jacquouille, who is stunned when he sees the machine.

While the postman is putting the sheet metal of his car back in place, he sees the two medieval men approaching him, with a menacing look.

After a scuffle with the restaurant manager who threatens them with a gun, Godefroy flees on horseback and loses sight of Jacquouille who leaves with Ginette in the opposite direction.

When Béatrice introduces herself to him, he initially mistakes her for his betrothed, Frénégonde, before realizing that she is in reality his direct descendant.

After throwing the doctor out the window, Godefroy goes outside, ready to face an entire squadron of riot police.

She misunderstands parts of what he tells her, but manages to understand that Godefroy is from the family of Béatrice de Montmirail.

In the evening, Jacquart comes to visit them accompanied by Mr. Berney, president of a banking group who suffers from a toothache.

During the night, Godefroy wakes up Béatrice and asks her to teach him the history of France since the reign of Louis the Fat.

At the same time, the modern version of the ring begins to heat up and sizzle in a window of the castle, disturbing President Berney's meeting in the room.

Godefroy finds in the chimney (the last vestige of the medieval castle) a secret mechanism revealing an underground passage.

During this time, Jacquouille meets Mr. Berney's assistant, Fabienne Morlot, who still mistakes him for Jacquart's brother.

After breaking a piece of armor in the management office, Ginette and Jacquouille are chased by a dog that Jacquart, exasperated, has unleashed on them.

Béatrice then notices a note telling Godefroy to contact a certain Ferdinand Eusebius, a medium who turns out to be a descendant of the mage.

The Count dismisses them, but Jacquart, accompanied by the police marshal, arrives in the room to confront Godefroy.

At dinner, while Godefroy recounts his old exploits, Jacquouille returns to the castle with Ginette at the wheel of a Cadillac, and announces to his master that he can stay here, because he has found "the cure against rot": toothpaste.

Just as moved, Godefroy in turn drinks the potion and, after bidding farewell to his descendant, recites the formula.

Jacquart wakes up stunned in the mud, surrounded by peasants and Godefroy's men, and, disoriented, runs after the man he still thinks is cousin Hubert, in desperation and confusion.
