The story opens with Russell Tymball, a nationalist Earthman, gaining possession of a Lhasinuic dispatch ordering the evacuation of Earth's human population and the planet's destruction. This will deal a death-blow to Loarism, and set the stage for the Second Galactic Drive, a planned Lhasinuic offensive against the disunited human worlds of the galaxy. Tymball uses the dispatch to convince Loara Paul Kane, head of the Loarists, to join in a second Terran rebellion against the Lhasinu. When a young Loarist pilgrim named Filip Sanat discovers two Lhasinu skulking around the Memorial in New York, Earth's most sacred structure, discussing the upcoming destruction of Earth, he rushes out, rouses a crowd, and starts a riot. When the Lhasinu attempt to force their way into the Memorial to arrest Sanat, they are overcome by Tymball's rebels and a human mob. Within a day, the Lhasinu are driven from New York City, and Sanat is sent out of the Solar System to enlist the help of the other human worlds.
