This entry in the courtroom telefilm series finds counselor Perry Mason (Raymond Burr) stepping in to defend Sheila Carlin (Mariette Hartley) — a radio shrink who’s a friend of Perry's loyal secretary, Della Street (Barbara Hale) -- against a murder charge. It seems that after the detestable station owner (Regis Philbin) shifted all the hosts' time slots to make way for music shows, someone bumped him off ... and set Sheila up to take the rap.
