Asgarthus (Az) Anderson, Portland teen, is slowly going blind and there is nothing he or medical science can do to stop it. While he tries to deal with his impending loss of sight, he finds out that he has developed another ability—that of a form of psychometry. In Az's case, he can see people and events in objects that have been touched by strangers, but only the most recent happenings. His ability amazes and frightens him, and at first, he doesn't know how to deal with it. His girlfriend, Lynn Wong, is also frightened, but she stands by him as he tries to work through his newfound condition. Things change when the local police as well as the FBI find out about his abilities, and soon, Az is working as a profiler of sorts for them, hunting down criminals. However, another case surfaces, one that baffles Az as well as everyone else. A killer is loose. The authorities have dubbed him the Silent Killer, as he creeps and kills silently and leaves no traces. For some reason, Az can't get a fix on him, and he doesn't know why. The killer, though, knows more about Az than is thought possible, and now, Az and Lynn must do everything in their power to avoid becoming his next victims.
