Classic 70s television cop-drama, starred Michael Douglas and Karl Malden. I believe there was one season where one or the other of them was absent. I think the first season had Karl Malden but not Michael Douglas. Fairly typical series but pretty good. Its always fun to catch a little air on those San Francisco hills. If this show were current, I think the Karl Malden character would be beating confessions out of a few suspects, but back then it was exclusively 'by the book.'
