Résumé: Only hours before the apocalypse begins, a Saturn VI rocket launches bearing three astronauts: Captain Boyd Ellis, United States Air Force; his fiancée, Jill Malden; and Japanese physicist Ikei Yashida. Weeks later, after the post-apocalyptic radiation has subsided to safe levels, their space capsule lands upon a melting Greenland ice field, where the three ally themselves with Kuno, a 3rd-century Goth revived from his ice-encased suspended animation.
The four encounter a Russian scientist/cyborg in Canada, where they commandeer a futuristic jet plane; undersea dwellers; and brutish U.S. military survivors, among others.
