While being apprehended, a suspected serial killer is injured and falls into a coma.  Four years later he awakens with no memory, unable to even remember his own name, much less the crimes he supposedly committed. The team uses brain fingerprinting and must find a way to prove his guilt without stirring his killer instincts.
