The Undefeated

A Union Cavalry outfit is sent behind confederate lines in strength to destroy a rail supply center. Along with them is sent a doctor who causes instant antipathy between him and the commander. The secret plan for the mission is overheard by a southern belle who must be taken along to assure her silence.

Detective Matthias Breecher, hired to track down the worst of the Confederate war criminals, roams the Old West seeking justice. His resolve is tested when he meets a determined pioneer woman who is far more than she seems.

Questions arise when Senator Stoddard attends the funeral of a local man named Tom Doniphon in a small Western town. Flashing back, we learn Doniphon saved Stoddard, then a lawyer, when he was roughed up by a crew of outlaws terrorizing the town, led by Liberty Valance. As the territory's safety hung in the balance, Doniphon and Stoddard, two of the only people standing up to him, proved to be very important, but different, foes to Valance.

Leon Alastray is an outlaw who has been given sanctuary by Father John, whom he then escorts to the village of San Sebastian. The village is deserted, with its cowardly residents hiding in the hills from Indians, who regularly attack the village and steal all their supplies. When Father John is murdered, the villagers mistakenly think the outlaw is the priest. Alastray at first tells them he is not a priest, but they don't believe it, and an apparent miracle seems to prove they are correct. Eventually, he assists them in regaining their confidence and defending themselves.
