Derek Cho, the film's protagonist, tells the audience about the ID-7 virus, or "Red Eye" virus, that has been spreading throughout the world. It infects neural pathways, removing all inhibition and moral integrity, and in turn, causing people to act out their darkest impulses. While the virus is not lethal, those infected by the virus may find themselves driven to kill. The first known case of murder driven by ID-7 was committed by Nevil Reed, who stabbed a coworker, but was not deemed liable due to the influence of the virus. Derek, a lawyer at Towers and Smythe Consulting, works for the firm that handled Reed's case; he began his job full of optimism, but ended up back-stabbing, cheating, and finding loophole after loophole in order to work his way up the corporate ladder and get a corner office.
