Gardner Elliot is the first human being born on Mars, the son of an astronaut who embarked on a space mission. The young man has only met fourteen people in his sixteen years of life, and does not even know who his father is. But, eager for answers, he looks for steps on the origin of his progenitor. Thus, it initiates a peculiar friendship at a distance with Tulsa, a smart adolescent of Colorado that lives on Earth.

At last Gardner has the opportunity to travel to the blue planet to experience all the wonders he has always read, meet Tulsa and find his father.
