In the near future, humans, hybrids and robots live side by side and all criminals, regardless of their genetic make-up and those who are deemed extremely dangerous, are contained on an island prison run by a psychologist called Dillon Springs. His experimental work utilizes prisoners to facilitate advancement to society through instigated conflicts and death, but Raoul, a robot guard, suddenly starts to develop a very human conscience when he discovers that five of the human, hybrid and robot prisoners are actually innocent. Raoul's discovery leads him to the underground City of Exiles and the Slave Trading Market, where humans, robots and hybrids are usually, illegally traded where he then has to track down a human/robot hybrid hacker called Brainiac. The hybrid hacker must then help him hack not only the prison system but also Dillon Springs mind, in order to help the five innocent prisoners escape before they are due to be slaughtered and terminated.
