This film begins with a scout by the name of "Adam Reed" (Rory Calhoun) being brought to a Cheyenne chief named "Fire Knife" (Lee Van Cleef) to discuss a matter of utmost concern. At this meeting, Fire Knife tells Adam that a U. S. Army is in violation of a treaty that states that no forts are allowed to be built in that section of Wyoming. Fire Knife further states that, unless the fort is immediately abandoned, the Cheyenne will kill everyone inside and then burn it to the ground. He then gives Adam a yellow tomahawk to give to the commander of the fort to show that the Cheyenne mean business. With that, Adam is released and goes to deliver the message to the commander of the fort. Unfortunately, when he tells "Major Ives" (Warner Anderson) the message, rather than abandoning the fort, the order is given to speed up construction on it instead--and this has drastic consequences for all involved. Now, rather than reveal any more, I will just say that this turned out to be an okay movie due in large part to the number of solid actors involved. Admittedly, the plot was fairly standard and the ending was somewhat predictable, but even so it was worth the time spent and I have rated it accordingly. Average.
