When the cure for some means death for others, how far will you go to save your own? Yulia Szymanski is a murderer and one of the best hackers of the century. Her mission: break her brother out of a high security jail before he dies of a rare genetic condition. On her trail is Biothreat Agent Skyler Donohue, a decorated Muay Thai fighter with a strange fascination for corpses. The obstacle to overcome: an invisible, deadly disease that strikes at random and has the city of Liasis locked in a bioterrorism siege. When the latest to fall ill is Skyler's best friend's daughter, Skyler wants to drop the Szymanski case to chase the baffling pathogen that nobody is able to isolate. What she doesn't know is that finding Yulia is the only way to stop the epidemic and save the child's life.
