In the later half of the twenty-first century, Jobe Corithese is hired to track down some missing people who are believed to have been kidnapped. He accepts this job after gaining information about the person who hired him, but the fact that he is being hunted by nearly every law enforcement agency on Earth will complicate his assignment considerably. So he decides to track down the only person he believes he can trust to help him complete the assignment, but the only problem is that this person, Sid Tyko, blames Jobe for his nearly dying during their first meeting. However, he does agree to help Jobe, but only because he is offered a large sum of money for his services.
Then with Sid in tow, Jobe goes to join his assistant, who happens to be an android who prefers to be called Gus, who has been heavily modified by all of his previous owners to the point where he has developed a rather unique personality to go with his impressive set of skills.
The three of them then leave Earth behind and begin their search for the missing people on a space station called The Rim that orbits Earth's moon. Their search takes them to various places on The Rim, and then to the moon itself, where they find the people they were looking for, but also begin to uncover secrets that they are not meant to know. They soon learn that their assignment will be anything but easy, as they are pitted against criminals, soldiers, and people employed by various law-enforcement agencies, while trying to unravel a larger conspiracy that they have suddenly learned they are a part of.
