The next exciting adventure for Uncle Pete and TM sees them prepare for an Arctic expedition to get, Berg, the little polar bear, back to his family. Gathering together their snow gear, they fit skis on the plane and head north with Berg. When they arrive where the family were last seen, the snow has melted and there is no sign of the bears. A passing whale tells the team they have been captured and taken off in a very sinister looking black ship. There is excitement aplenty, with wooden squirrel helicopters, tunnels, bears in disguises, evil animal hunters and a daring rescue. And so, the third quest for Uncle Pete and TM begins.
