The Streets of San Francisco

Solitaire (3x23)

Air date: Mar 13, 1975

Against his will, Stone gets a new partner while Keller recovers from a gunshot wound. Hippie-haired narc Al Walczinsky isn't too happy about having Stone as a partner either. Together they try to break up a narcotics ring that's gone murderous -- until Stone suspects that Walczinsky's in on the racket.
