The Trigger Trio has as the 3 Mesquiteers Ray Corrigan, Max Terhune, and Ralph Byrd. Once again the Trio does quarrel, but in the end unite to foil the bad guys.Which in this film is a rancher who has a herd with hoof and mouth disease. Cornelius Keefe is threatened with ruin if his herd is destroyed so he changes the brand on the dead cows to that of Robert Warwick. Later on he kills Warwick orphaning both Sammy McKim and Sandra Corday.No orphans ever went unaided by the Mesquiteers. But in this case Corrigan has been appointed a deputy cattle inspector for the duration of the quarantine. That puts him in conflict with Byrd who wants to aid Corday and McKim. Eventually it's all straightened out.A tale told thousands of times over in the old west of Hollywood.

If you've seen the Clark Gable version of "Call of the Wild", then you'll no doubt remember that huge St. Bernard, 'Buck'. Well, it turns out Buck had a bit of a career beyond this one film--and here he is playing himself in "The Trigger Trio". So, as a fan of old films, I was thrilled to once again see him. Plus, in the end it is Buck who saves the day...yee-haw! Unfortunately, Buck is the most interesting character in the film.The film does have a very unusual plot--that's for sure. Apparently, a baddie rancher has found hoof and mouth disease among his herd. Instead of reporting it or killing the cattle, he re-brands them and puts them on another ranch! Ultimately, this jerk is willing to do about anything to hide this disease, as the cure for the disease is to kill all the cows! And, because he's so bad, he's willing to do much more...Apart from a novel plot and Buck, there isn't a lot going for this B-western. It's too low energy and the three Mesquiteers just aren't interesting. Now don't think this means every Mesquiteer movie is dull. This is because the makeup of the three actors varied wildly over the years--with many different actors in the roles (including John Wayne). Some had nice distinct personalities--some did not. This crop didn't.
