After two weeks' pre-emption due to the 1976 Winter Olympics, Streets of San Francisco returned to ABC's Thursday schedule with a typically perplaxing case for SFPD detectives Stone (Karl Malden) and Keller (Michael Douglas). Four judges have been murdered, and in each case an obsolete pamphlet on disbarrment proceedings is found near the body. Halfway through the story, the audience discovers that the culprit is the demented son of a disbarred lawyer, who intends to get even with the "bleeding hearts" who ruined his father--but how long will it be before the Law is able to end this bizarre vendetta. Jean Hagen, best remembered as the screechy-voiced movie queen in Singin' in the Rain, makes one of her final appearances in this episode. ~ Hal Erickson, Rovi
