A US government germ warfare lab has had an accident. The first theory is that one of the germs has been released and killed several scientists. The big fear is that a more virulent strain, named The Satan Bug because all life can be killed off by it should it escape, may have been stolen.
Sam Gifford remembers : In prewar years he was an arrogant southern cotton plantation owner, married to the daughter of a colonel. At the beginning of the war he was mobilized with his National Guard unit as a sergeant. Came the day when, revolted by the cowardice of his lieutenant, who had fired at his own men, he hit him. Downgraded, he was sent to a disciplinary battalion. Sam now discovers his new detachment, his new commanding officer, just another cowardly brute, Captain Waco Grimes. While in combat, Sam will gradually become closer to the privates, working-class people he used to despise. He will become another man, a better man.
