In 1969 the Apollo moon landing is to be televised internationally but
at a country fair in England a small boy named Jim meets the 90-year-old
Julius Bedford who tells him that,in 1909,as a struggling writer,he met
eccentric Professor Cavor,inventor of Cavorite,a gravity-defying
substance which they used to build a sphere,which took them to the Moon.
Captured by ant-like Selenites,Bedford was anxious to make his escape
but Cavor was happy to stay and communicate with the Moon-dwellers. Back
on Earth Bedford hears via wireless that Cavor was forced to kill
himself and the Moon-dwellers to prevent them from invading Earth. As
Jim watches the Apollo landing with his parents back in the present he
sees a Selenite,hiding behind a lunar rock,peering at the astronauts.
