William Conrad stars as J.L. McCabe, an ex-cop who is working as a district-attorney. Co-stars include Joe Penny as a special investigator, Alan Campbell as McCabe's assistant D.A., Karen Austin plays the deputy mayor-and Max the Dog, McCabe's aging, half-deaf bulldog, who will probably steal the show. Anne Francis shows up as Dixie, a former big-band singer who owns the bar and grill McCabe favors.
William Conrad stars as Jason Lochinvar "Fatman" McCabe, a rotund, cigar-chomping district attorney with a bulldog's tenacity. Along with his suave investigator, Jake Styles (Joe Penny), he secures convictions for some of Southern California's most bewildering crimes, bringing to justice a despicable mix of killers, thieves, and rapists. Assisting the odd couple are Jake's sunny assistant Derek, his fork-tongued secretary Gertrude, and of course his wrinkly old bulldog Max. The show, which originated in a two-part episode of MATLOCK, was itself later spun off into the series DIAGNOSIS: MURDER.
