After an accidental nuclear disaster, only 40% of the population remains and vast areas of once-fertile land are now nothing but barren desert. However, there is a legendary haven, a place established for the world's most brilliant minds to work without being troubled by the outside world, a place which escaped the disaster, a place which is as idyllic and free from worldly troubles as it was before the nuclear winter. This place is Oz.
Felicia Epstein's genius brother Leon left years ago to find this legendary place and was never seen again. But now, while Felicia is on a trip to see her uncle, a cybernoid with the appearance of her mother is found, and it bears a message from Leon stating that he has found Oz and has sent the android, called 1019, to bring her there.
However, all is not what it seems. What kind of dark secrets lay in Felicia's mother's psyche that were transferred to 1019? Why are subsequent cybernoids, all with her mother's appearance, dispatched to replace her previous cybernoid guides, each with a distinct personality of its own? What kind of place is Oz? What are its goals?
