"After a freak accident on the Star Express roller coaster, 13-year-old Mary Von Rathen begins to lean. Doctors cannot help her, so she is sent by her selfish mother and hen-pecked father to a private school in Sodrovni. Mary escapes and joins the Robertson Circus, where she remains for several years, until she hears from newspaper editor, Stanislas Sainclair, that a scientist, Axel Wappendorf, might be able to help her. Wappendorf is working on a rocket to reach a planet that could hold the secret to Mary’s trouble. Meanwhile, artist Augustin Desombres has run away from the busy world and buys an empty building on the High Plains of Aubrac in the French countryside. He begins painting murals of strange globes. Now a young woman, Mary decides to join Wappendorf in the rocket. On the alien planet, they discover an area with many globes where she has a chance meeting with the artist."
