Arthur is a lively ten-year older whose parents are off looking for work, whose bizarre grandfather has been missing for many years, and that resides with his grandma in a place house which, in just two weeks, will probably likely be repossessed, ripped down, and become a block of apartments unless Arthur's grandfather proceeds to sign some papers and also repay the family debt. Arthur discovers that the secret to success lies in his descent into the land of the Minimoys, monsters no bigger than a tooth, whom his grandfather helped relocate into their garden. Somewhere among them will be hidden a pile of rubies. Can Arthur function as stout heart and save the day? Romance beckons as well, and also there lurks also a villain.
