Synopsis by Hans J. Wollstein
Although the entire room disintegrates, Terry (Ralph Byrd) and Snapper (Lee Ford) emerge unscathed from Boroff's impenetrable glass chamber, glass being the only material not affected by the disintegration gas. Jean Norman (Maxine Doyle) brings a surviving vial of gas to be tested by her brother, Dick (Allen Connor), much to the consternation of Boroff (Bela Lugosi), who sends one of his thugs, Dodds (Carleton Young), to grab the girl. Jean is lured into revealing the location of the Norman laboratories and Dodds and the mute Thorg (Richard Alexander) are assigned to storm the place. The plan backfires, however, and Terry learns of the whereabouts of Jean. Having rescued the girl, the hero once again comes face to face with Boroff's henchmen, who this time get the upper hand. As the episode ends, Terry is left to die at the bottom of an elevator shaft.
