A mischievous (and voraciously hungry) young dragon flies through the Milky Way eating up every shiny object in his path, including the Sun. The Earth is plunged into darkness and everyone in the village of Tomtitou is in despair—until a boy named Hugo, armed with a telescope, makes contact with a mysterious star called Aramis. Together, they embark on a daunting celestial adventure. Will Hugo and his new friend be able to recover the stars?
