Five survivors kept alive to be tortured
During a world war, the American, Soviet, and Chinese military supercomputers merge into one sentient machine, AM, which kills all of humanity except five people: Ted, Benny, Gorrister, Nimdok, and Ellen. For 109 years AM keeps them alive and nearly immortal beneath the earth, torturing and deforming them, then lures them on a starving trek to ice caves, where they find a cache of canned food and nothing to open it with. Ted and Ellen then kill the other three, and Ted kills Ellen; in revenge, AM turns Ted into a mouthless, gelatinous blob that cannot harm itself, and keeps him alive forever.
