PROBLEM ONE: An Earthman is suddenly and mysteriously transposed to an alien planet: an utterly empty, completely lifeless outpost of a far-flung galaxy. The Earthman has no idea where he is, how he came to be on the godforsaken world, or how to get home.
PROBLEM TWO: For company there is only a computer: a computer which has all the answers to all of the Earthman's questions. But the computer is programmed to give information only to those properly trained and qualified to understand it. The Earthman is not.
SOLUTION: The Earthman must outwit the rigid electro-mechanical being to leam the secrets that will get him back to Earth . . . but the solution is the biggest problem of them all!
