Adventure awaits in your own backyard.

Ten-year-old Arthur, in a bid to save his grandfather's house from being demolished, goes looking for some much-fabled hidden treasure in the land of the Minimoys, a tiny people living in harmony with nature. Like all children of his age, Arthur is fascinated by the bedtime stories his grandmother tells him. His dreams are full of African tribes and incredible inventions drawn from an old book of spells that belonged to his grandfather, who disappeared mysteriously four years ago. In just three days, he must find a way to the land of the Invisibles, recover a stolen treasure, battle an invading force of mosquito-riding warriors, defeat an evil wizard, win the heart of a very independent princess and somehow get back home again.
