Marion Warner inherits a ranch from an uncle. Stranded in the desert, she encounters Blandy, a white man raised by Navajos who believes her land actually belongs to the Indians. A trading post owner, Morgan, aided by partner Blucher and hired guns Glendon and Lord, has been stealing from the Navajos and kidnapping women, including Yashi, who is held prisoner until Marion arranges her escape. An expert with a gun, Marion also rescues Etenia, the Navajo chief, after Morgan's men attempt to kill him.
Blandy is able to help Marion steal documents from Morgan's safe relating to the rightful ownership of the land. Blandy is taken captive and tortured as Marion realizes she has fallen in love with him. She sends for the law, Sheriff Joe Walker, then rescues him after he is taken prisoner. Walker then takes Morgan into custody as Blandy and Marion come to the aid of the Navajos and plan a future together.
