Arthur is a spirited ten-year previous whose mother and father are away searching for work, whose eccentric grandfather has been lacking for a number of years, and who lives along with his grandmother in a rustic home that, in two days, will probably be repossessed, torn down, and was a block of flats except Arthur’s grandfather returns to signal some papers and repay the household debt. Arthur discovers that the important thing to success lies in his personal descent into the land of the Minimoys, creatures no bigger than a tooth, whom his grandfather helped relocate to their backyard. Someplace amongst them is hidden a pile of rubies, too. Can Arthur be of stout coronary heart and save the day? Romance beckons as effectively, and a villain lurks.
