Former Cyborg Corps soldier Jasim Antar was relieved to come out of the war alive and looked forward to switching to a less violent line of work. But nobody wants to hire a brawny cyborg to do anything that doesn't involve brutalizing people on a daily basis. Stuck working as a debt collector alongside an eccentric pilot who enjoys knitting gifts for her grandkids when she isn't blowing people up, Jasim longs to find a more peaceful existence.

But peace is elusive when you have a violent past. While on a routine mission, Jasim comes across the body of a soldier he served with during the war. He soon learns that someone is murdering former members of the Cyborg Corps, men who should be extremely difficult to kill. And he's next on the list.

Jasim steels himself to reach out to the one person he's certain can help, his old commander: Colonel Leonidas Adler. Adler is strong, smart, and deadly, good traits to have in an ally. Unfortunately, he remembers Jasim as a misfit rather than a model soldier, and convincing him to join forces may be even tougher than finding and facing the killer.
