A mysterious terrorist calling himself Kilohertz has the ability to intercept nationwide TV broadcasts. Both the GSA and Mutant X believe he is a New Mutant. The GSA sends out fresh young mutant-agent Renfield, while Mutant X try to Kilohertz him down before the GSA can. Both of them track the transmission to a TV station, and figure out Kilohertz is a young staffer, Barry Stirling. Mutant X gets to him first, getting him away from Renfield, who is forced to undergo torturous "retraining" at the hands of Eckhart because of his failure. Meanwhile, Kilohertz/Sterling comes to believe that Mutant X are a danger, since they try to sedate and capture him when he starts raving about throwing the world into chaos. He manages to escape, and they recapture him, but he takes over the Sanctuary systems. Adam manages to expel him from the system, and Brennan scrambles the comm units so Kilohertz can't get back in. Barry flees to the GSA, but is captured by Renfield (who has the ability to "freeze" people) and put into the tanks for further experimentation
