Jack takes over the control room and threatens to flood the containment with radiation unless he is allowed to make a public statement. Kimberly and Jack prepare for broadcast while awaiting the arrival of a photography team. Meanwhile, the plant officials have brought in a SWAT team to break into the control room, and other loyal employees are preparing to trip the generator and turbine, thereby forcing the reactors to do a total plant scram in order to prevent Jack from flooding the containment. Jack's assistant, Ted Spindler (Wilford Brimley), warns them that a scram is just what Jack is afraid of, but they don't listen to Spindler either.
Everything comes together when the photography team arrives and Kimberly goes on the air. She introduces Jack, who begins to tell the story of what happened during the last "event" and how close the plant came to a disaster. As Jack tries to explain the very complicated workings of the nuclear reactor, Spindler (under orders) cuts the wires that trip the generator. An alarm starts to sound, alerting Jack that the reactors are about to scram. He starts screaming "No! No!" and attempts to rectify the trip. Suddenly, the SWAT team breaks through the door and shoots Jack multiple times in the back. Before he dies, he manages only to whisper into Kimberly's ear, "I feel it", referring to the shaking and shuddering that indicates a scram had begun. On the control screens, everyone watches helplessly as the feed water pump breaks free. Minutes pass as the event plays itself out. When Spindler checks the computer feed, he finds that the event is over and the reactor is stable. Everyone breathes a sigh of relief.
Outside of the plant, multiple TV crews have arrived and KXLA has managed to set up another Cam. Bill Gibson (James Hampton), PR man for the power plant, is conducting interviews that depict Jack as a drunk and a nutcase, assuring the public that they were never in any danger. Angered by their slander against Jack, Kimberly goes back on the air and, although she is finding it hard to maintain composure, she manages to interview Spindler, who finally admits that Jack was not a nutcase and upholds Jack's warning that the plant should be shut down and inspected. In the final scenes, Kimberly's broadcast ends and KXLA goes to a commercial for microwave ovens. Test bars cover the TV screen, the screen goes dark, and credits roll.
