Delphi Corporation systems engineer Hugh Williams is sent with a support team to investigate why communications between Earth and the Cradle have been cut off. However, when they land, they find the facility mysteriously devoid of human activity. The Cradle is then struck by a sudden moonquake, which separates Hugh from his team and knocks him unconscious. He is revived by a child-like android girl, Pragmata D-I-0336-7, who Hugh dubs "Diana". He quickly discovers that the Cradle's AI administrator, IDUS, has gone rogue, and it begins sending hostile robots to eliminate him. Diana assists Hugh in combat by using her abilities to hack enemy robots, making them vulnerable to Hugh's weapons. However, she has no knowledge of why IDUS went rogue or what happened to the Cradle's human staff.
