JEFF CHANDLER does a creditable job as tough Army Major Kenniston at Fort Thorn with a hatred of Confederate rebels. His sister-in-law LINDA DARNELL wants to go back to California from the New Mexico fort, but Chandler is smitten with her and tries to prevent the strong-willed lady from having her own way.
Meantime, two other men have their eyes on Linda--Confederate Col. Clay Tucker (JOSEPH COTTEN) and dashing Capt. Mark Bradford (CORNEL WILDE), both of whom fall for Major Kenniston's sister-in-law.
Seems the Yankees are willing to free Confederate prisoners if they're willing to help them fight off the Indians surrounding the fort. While this is the major plot driven device, the romantic sub-plots involving Chandler, Darnell, Wilde and Cotten get a fair share of time too.
It all comes together as an above average cavalry western under the crisp direction of Robert Wise, who makes the most of some excellent camera work in the rugged western settings. The story has some interesting components but takes time in setting up the various conflicts. Nevertheless, enough action and a little romance to satisfy most viewers of the genre.
