Gluttonous best friend Alceste, rich boy Geoffrey, dimwitted Clotaire, quarrelsome Eudes, eccentric Rufus and spoiled top student Agnan already have plans for the future.
The next few days, Nicholas becomes determined to please his mother in everything, even attending a tea party with her friends, where he spends time with a girl named Marie-Edwige and her girlfriends.
Nonetheless, Nicholas' parents still take him to the woods and he refuses to come out, forcing them to push the car back home when they cannot persuade him otherwise and spend the rest of the day arguing.

The acting from the adults has a slight pantomime edge to it, but this complements the source material and gives a real sense of the way in which children tend to view grown-ups as larger-than-life.

"[27] Similarly, Bernard Besserglik of The Hollywood Reporter also commented, saying that this film adaptation is "technically proficient" and "[features] two of France's best comic actors.
