A young aspiring artist travels to an art school in Scotland, where she starts the creation of an ambitious work: an aquarium inhabited by an axolotl, a small Mexican amphibian.
The relationship she establishes with this creature leads her to a moral crisis that will call into question her understanding of the art world and her life decisions. However, she moves on.
In the same way that the Axolotl adapts to this new aquarium installed in a Scottish art school, the author herself integrates into a society different from her own. Both the axolotl and the author are beings living outside their own habitats and customs, where the readers can follow them behind the glowing glass.
