The two-part opener of Streets of San Francisco's fifth and final season marks a major transition, as SFPD homicide detective Mike Stone (Karl Malden) loses his longtime partner Steve Keller (Michael Douglas) and gains a new one, athletic young inspector Dan Robbins (Richard Hatch). But before Keller can leave the force to launch a teaching career, he and Stone are faced with the daunting task of rescuing a busload of jurors who have been kidnapped by a "family" of dangerously misguided revolutionaries, who demand the release of their imprisoned cohorts. This two-parter is clearly inspired by the Patty Hearst kidnapping, with former Partridge Family regular Susan Dey delivering a shockingly powerful performance. As a publicity ploy, the season opener features fourteen guest stars, including Marion Ross (then appearing regularly on Happy Days, Barry Sullivan, Dick Van Patten, Norman Fell and Doris Roberts--not to mention such stars-to-be as Anthony Geary and Ron Glass. ~ Hal Erickson, Rovi
