hal (fictitious character)

Mankind finds a mysterious artifact buried on the moon and with the intelligent computer HAL 9000, sets off on a quest to Jupiter.

The body of Frank Poole, murdered by mad computer HAL a thousand years earlier, is found and revived to a world of peace and plenty, but in his attempts to understand the entity composed of his former deputy Dave Bowman and a copy of the now-sane HAL, Frank learns that Earth is slated for destruction.

The spacecraft Discovery journeys to the outer edge of the solar system, and two navigators become uneasy when Hal, the craft's talking computer system, demonstrates unusual behavior.
