Ironside (Raymond Burr) invests in a play staged by an avant-garde theater troupe. When one of the actresses dies of a heroin overdose during rehearsal, the Chief takes it upon himself to find the killer, prevent further murders--and, incidentally, protect his investment! Featured in the cast is Sally Struthers, whose career was then just taking off thanks to her exposure on the new CBS sitcom All in the Family. This episode was filmed at the old Pasadena Playhouse, onetime training ground of series star Raymond Burr. ~ Hal Erickson, Rovi
