Confined to a wheelchair, 11-year-old Finn looks forward to the visits of his Uncle Henry and the unbelievable stories of his adventures. When Henry goes to the Arctic to look for his father's lost ship, the stories become increasingly fantastical, straining even Finn's desire to believe everything his uncle tells him, until he joins in the adventure himself!

Expect aliens, a wise-cracking fox, singing bears, the most powerful device in the universe and some very peculiar snow.
