Ironside (Raymond Burr) stage-manages an elaborate ruse to bring mob kingpin John Trask (a pre-Hawaii 5-0 Jack Lord) to justice. Hiding the fact that a gangster who'd planned to turn state's evidence has been murdered, Ironside leads Trask to believe that the dead witness is still alive and really to spill everything. The rest of the episode is a tense waiting game, with Ironside hoping that Trask's nervousness will lead who to take the proverbial "one false step". ~ Hal Erickson, Rovi
