I first saw this one back in the early 90's when it showed up on midweek daytime TV here in the UK. I remembered it being an enjoyable enough, if unremarkable, effort. Having just seen it again I do have to say that that original assessment still holds. Brock is a burnt-out NYC cop who retires from life in the firing line of the Big Apple and retires to a ranch in the Californian countryside. On arrival, his Native American ranch hand is arrested for the murder of the local sheriff. The situation appears fishy though and before long Brock is recruited to investigate.
This is one of a very specific type of TV movie which was a pilot for a series that never was. I can see why they thought they might have a workable idea to be honest, as detective dramas were ten-a-penny back in the 70's, while the whole fish-out-of-water idea is one in which many plot-lines can sprout from. Yet it remained a one-off film and was not picked up. Truthfully, they could have worked out a better story-line I reckon, as the central mystery is not especially interesting. Nevertheless, it's still a decent enough film which benefits from its TV movie charm and, in Richard Widmark, it had a good main star.
