This short film is a combination of live-action and animation. It is done in the style of the chalk drawings seen in the original "Mary Poppins" film and was produced exclusively for the 40th Anniversary Special Edition DVD released in December of 2004. Julie Andrews and two children magically enter the animated world of the chalk drawings to experience this whimsical tale based on one of the chapters from the original series of "Mary Poppins" books.
After the fall of Tobruk in June 1942, U.S. Army sergeant Joe Gunn leads his tank into the Sahara desert, in order to evade advancing Rommel's forces and reach Allied lines. Along the way he picks up few Allied soldiers, but soon they are running out of water. They find water at the ancient well, but the well is a goal of an entire German battalion. Despite the impossible odds, Sergeant Gunn decides to defend the well.
