In the savage underworld of the late 21st century, a man lives and dies by his blades, bullets, and honor. Beret is a "Null", a criminal who does work against the giant corporations controlling the world. Part thief, part hit man, Beret is the best of the worst in Chicago. He's the best there is, but he's still a man with problems. His girlfriend, Lucy, is dead, but he sleeps with prostitutes willing to run the computer simulation of her, allowing him to still be with her. Then, not only does Lucy start to malfunction but people close to him start getting killed. Beret meets his new mechanic, JoJo, the person with the skills to work on the tools of his trade. The attraction between the two is immediate, but both attempt to supress it, and their partnership is effective and profitable. With sparks between them, can they maintain a purely business relationship and find the killer before being killed?
