Humanity finds a mysterious object buried beneath the lunar surface and sets off to find its origins with the help of HAL 9000, the world's most advanced super computer.

A party of children playing on a moor lose their toy aeroplane which flies through the window of a lonely tower. A multitude of objects found in the town to help rescue the aeroplane prove very difficult to get out to the moor, involving them with barrows, traffic and the local hunt. At last they succeed in entering the tower only to get trapped themselves. Finally Neddy, the donkey, shows them the way out.
