Season Thee of Ironside begins as wheelchair-bound detective Robert T. Ironside (Raymond Burr) and his team set their sighs on prolific con artist Raymond Otis Baker (Joseph Campanella), who specializes in bilking little old ladies out of their life savings. Unfortunately for Baker--or, as he is now calling himself, Mr. Braithwaite--his most recent victim was the aunt (Beah Richards) of Ironside's bodyguard Mark (Don Mitchell). In order to trap the elusive "R.O.B.", Ed (Don Galloway) and Eve (Barbara Anderson) pose as a wealthy couple, ripe for plucking. But the plan goes awry when one of the villain's accomplices recognizes Ed from an earlier sting operation!
