A young girl asking her parents why they put their money in a squirrel.

The ad opens with a shot of a Caisse d'Epargne bank branch. People are walking in and out. A young girl with glasses asks her parents why they put their money in a squirrel. The scene then shifts to a forest where squirrels are gathering nuts and interacting cooperatively. The ad returns to the girl, who then states she is the little mouse. The final scenes show the bank branch again with text overlays about being cooperative and regional, ending with the bank's logo and slogan.
