When "Welles" (Michael Sarazin) is caught after an audacious break in to sabotage a top secret government lab, he claims to have been so traumatised by the whole experience and explosive aftermath that he cannot remember anything about who he is, or why his was there. That deduction falls to "Tuxan"...
