In this western, an idealistic and naive rookie cavalry officer is assigned to work with a cruel captain. He immediately gets on the crabby captain's bad side by trying to restart an affair with his ex-sweetheart. The woman is engaged to another who ends up getting killed by the Indians. This rookie, blaming himself for distracting the slain officer with his overtures to the officer's fiance, volunteers to act as a decoy to lure the renegade Apaches into a trap. It works, but many soldiers die. After the skirmish, the rookie has become a seasoned officer prepared to take his duties seriously. Back at the fort, he bids farewell to the woman as she begins her long journey back east.
