Pete Manders (Wynn Pearce), chief assistant to cartoonist Gabe Philips (Mark Roberts), cannot believe his good fortune when Philips sells him the rights to his popular comic strip "Zingy" at a bargain rate. Philips claims that he wants to retire from the daily grind and set up residence in the tiny artists' colony of Port Harmon, where he intends to become a serious painter under the name of Otto Gervaert. But that's only part of the story: Philips also wants to claim Manders' girlfriend Lesley Lawrence (Pamela Curran) for himself. When Philips--or Gervaert--is murdered, Perry Mason (Raymond Burr) must seek out clues amongst the denizens of Port Harmon in order to keep Manders out of the Death House. The supporting cast offers a wide and varied range of acting styles, from the fluttery mannerisms of veteran comedienne ZaSu Pitts to the pompous pontifications of perennial "heavy" Victor Buono.
