In the waning days of WWI, a U.S. “Mystery Ship,” sets sail for the coast of Spain towing a submarine. Their mission is to find and sink a U-boat that has been especially effective in attacking Allied shipping. Posing as a harmless schooner, the mystery ship is in fact fitted with a formidable gun capable of sinking a U-boat. Stopping in the Canary Islands to refuel, the crew interacts with locals involved with Germans, and with Germans themselves, including the sister of the U-Boat commander, who is lurking offshore waiting for the coming battle.

In a seasonal special, Gordon Buchanan meets the animals who live in nature’s winter wonderlands. He reveals their survival secrets, from the polar bear mother who gives her cubs the best possible start in life to the owl that finds food hidden beneath a blanket of snow, plus the plucky penguins that huddle together to keep warm. Gordon also unwraps the lives of our favourite Christmas characters – those wonderful reindeer and our very own robin redbreast!
