Senator Stanton (James Olson) is the top traitor. The guy with the lost memory (Michael Sarrazin) and new face due to reconstructive surgery after the explosion is not the real intruder “John Welles”. The real John Welles died shortly after the explosion, and ruthless investigator Tuxan (George Peppard) used an agent (who had lost his girlfriend in an accident) as volunteer and deleted his memory to track the traitor, by observing who would contact him.
