Sofia and her cat Luna love to wander the Multiverse. Throughout their travels they have gone to worlds where there are still dinosaurs, or inhabitants who can change shape over and over again. In one of their adventures, they take their spaceship into a wormhole, a tunnel in space-time, and arrive at an extraordinary world called The Land of Infinity. There they will discover the guardian of the entrance Lewis, a robot who is always in a hurry and many other beings in the Infinite Hotel, which always has enough rooms to accommodate its numerous guests, coming from worlds as distant as they are fantastic.

Throughout their journeys through different universes, they will learn that mathematics and numbers are a game that allows them to better understand both the world around them and themselves. And that the most wonderful realities that may exist are within the reach of your imagination, with the help of your curiosity and the learning obtained on your travels and with the knowledge of the new friends you make along the way.
