Just when you thought KARR was done, much to our surprise and by Michael's priceless expression when he sees him in the episode for the first time KARR is back. KARR manipulates a young man into helping him even going so far as threatening the man's girlfriend. Bonnie redsigns the laser from the first episode to stop KARR but when KARR steals the laser and puts it on himself Michael and KITT have to battle KARR with the deadly laser. After freeing KARR's forced helper and girlfriend we have a "final" showdown that may top the battle from the first epidode.
Who knows what would happen next as KARR's computer was still activated at the end of the episode?
