Dr. Stuart Peters (Michael Forest) arrives in Los Angeles from upstate New York, with his ne'er-do-well younger brother Jory (Scott Marlowe) in tow, to take a job at NORCO, an energy research laboratory. After an odd encounter with a guard -- who tries to warn him away from NORCO -- he reports for work and immediately goes incommunicado for a week. When he reappears, Peters looks worn, haggard, and preoccupied -- and dies when something seems to explode in his chest. The medical examiner determines that the cause of death was a faulty heart pacemaker. The problem, for the police detective (Edward Asner) investigating the death, and for the victim's grief-sticken brother, is that the physicist was in perfect health and had never worn a pacemaker. They want to know what happened to him during the week he was unaccounted for at NORCO -- and why the staff, from the director (Kent Smith) on down, won't cooperate with the investigation.
