I remember this movie from the 70's. Mercedes McCambridge's performance has stuck with me all these years. I can still hear her singing "my hands are clean, my hands are clean and hey noni noni noni". If you saw the movie that will bring back memories. Yes, great buddy cop flick. The two lead actors had a great camaraderie. Someone killed Walter Brennan's family and just disappeared. For a small screen movie it was very good. The acting was very good. It was very suspenseful as you watched these two cops investigate and try to figure out how someone could kill a whole family and just disappear. I wish I could find this somewhere to watch again. Very satisfying.
