Steven and Sharon are just eight and ten years old and they are about to have a hair raising adventure in the wilds above Placerville. During the adventure they see something so extremely out of the ordinary, that they think they're dreaming.

Christmas Eve they are staying with their Granny when they find out that maybe what they saw wasn't a dream, but something real, something big.

They are whisked off to Dreamland by their Granny to visit with Captain Pengo and Tra to ride on the Wally Wally Maru, a gigantic dreamship that can take them anywhere in Dreamland they could possibly want to go.
