The story follows Charley, a man who discovers a mysterious "third level" at Grand Central Station that appears to be a portal to the past. On this level, he encounters outdated technology and fashion from the 1890s. Charley wishes to escape to Galesburg, Illinois through this third level to get away from the troubles of his present day. However, when he fails to reenter the third level, his psychiatrist friend Sam suggests it was just Charley's imagination seeking refuge from modern unhappiness. Later, they find evidence that Sam may have actually traveled to the past when they receive a letter from him dated in 1894 Galesburg.
