An upstanding doctor is transformed into a cold-blooded serial killer after being attacked by terrorists in Vietnam. Robert Smith is a respected doctor who teaches medicine at a university in Mexico City. During a trip to Vietnam, Dr. Smith is brutally assaulted by terrorists. Traumatized by the horrific event, the good doctor's fears are compounded by the discovery that he has been infected with an incurable disease. Now, as the urge to kill takes over, Dr. Smith embarks on a bloody rampage of murder and mayhem. In his warped perception, each new victim represents another shot at redemption, and he can't stop killing until he's regained his humanity. ~ Jason Buchanan, Rovi
