The unnamed Narrator lives in Woking, outside of London, in the early twentieth century. He tells the story of an invasion of Earth by Martians. The events start at the end of the nineteenth century, while Earth is being observed by Martians. Resources on Mars are running out, and the Martians, with superior technology, plan to conquer Earth. Astronomers witness the venting of gases on Mars, not knowing that it is the Martians launching their attack.
