In the uncolonized pampas of Argentina in 1870, Captain Martin, the commanding officer of a lonely outpost, confronts the problem of an ever-increasing number of deserters. Behind the plot to decimate the army ranks is a renegade soldier, Padron, who is in league with hostile Indians. By offering each deserter a captive woman, Padron has succeeded in amassing a band of outlaws bent on attacking and plundering villages. Determined to defeat Padron at his own game, Captain Martin eventually persuades his superiors that the soldiers at the fort must be provided with female companionship. As a consequence, prostitutes are removed from prisons, granted a military escort, and forced to make the dangerous journey across the pampas to the fort. The soldiers, with a few exceptions, obey their instructions not to touch the women until they reach their destination. Once the women arrive at the fort, their presence not only bolsters morale but also brings about the return of some of the deserters. When his ranks have swelled to their original size, Captain Martin leads an attack on the Indians and the remaining rebels and restores peace to the pampas.
