Henry and Anna are excited to be spending Christmas with Uncle Paul, the oddest of all their odd uncles. When he sends them up to the attic to fetch their Christmas present, which is "wrapped" in a riddle, they find themselves swept through the fantasy world of movies. With only the riddle to guide them, Henry and Anna climb the Empire State Building with King Kong, drink tea with Alice in Wonderland, and swing through the jungle with Tarzan. Will they get home again, or will they be singing in the rain forever?
En snurrig historie med et vell av filmkulturelle referanser som nok vil gå langt over hodet på målgruppen og kanskje også deres foresatte. Noe er heldigvis forklart bakerst i boken, som et slags "rollegalleri".
