A dangerous mission reunites STINGRAY SAM with his long lost accomplice, The Quasar Kid. Follow these two space convicts as their earn their freedom in exchange for the rescue of a young girl who is being held captive by the genetically designed figurehead of a very wealthy planet.

Arthur did as a boy what only grandpa, a fellow nature buff, did as an adult: pass, as white man, the Bogo tribe's tests of harmony with the natural worlds of trees, minerals and animals. To answer a mysterious call fro help from the Mimimoy people, he enters their world miniaturized. By the time he works out with friends it was a trick, the mastermind has already escaped, ready to strike in our world.

Maltazard, the Evil M, is now 7 feet tall and evolving among the humans, causing terror wherever he goes. His goal is simple: forming an army of giant henchmen and ruling over the universe. Meanwhile, Arthur is still a Minimoy, and thus in a state where he's unable to fend him off. With the help of Selenia and Betameche, he hatches a plan to regain his usual size: all they must do is infiltrate Arthur's house through the pipeworks, catch an electric train from his bedroom to his grandfather's study and find an elixir that will make him grow back to his human size. Sounds simple enough, if it weren't for Darkos, Maltazard's own son, hot on their tails.
