Gabriela, Manuel and Leonardo are three friends who accidentally start a rocket that takes them to space. Their journey through space takes them to different planets and strange worlds. Throughout their journey, they have the help of Maqui, an on-board computer. Maqui helps them learn about the universe. The spaceship runs out of water, and the kids urgently look for more. They arrive at a planet full of water, and the habitant that greets them tells them of great flood that almost made the whole continent disappear.
