The last mortal in a world of immortals, Nemo Nobody begins reviewing his life at the age of 120, trying to determine if he made the right decisions.
In 2092, humanity has conquered mortality through the endless renewal of cells. The world watches in fascination as the 118-year-old Nemo Nobody, the last mortal on Earth, edges towards death. Curious to know of life before quasi-immortality, they interview Nemo. Dr. Feldheim, a psychiatrist, uses hypnosis to help Nemo recall some of his memories, while Nemo relates other memories to a journalist. As he is prodded, Nemo makes contradictory statements. He recounts his life at three primary points: at age 9, when his parents divorced; at age 15, when he fell in love; and at age 34, as an adult. All three unfold into their many possible outcomes.
