On Simpson's orders, the outlaws plan to kill Buffalo Bill by luring him into their hiding place and manipulating the door so that a gun automatically fires at him when it is opened.

The next day, Buffalo Bill assigns two Indian scouts, Young Bird and White Mountain, to watch the road near the hideout.

To avoid being exposed, Simpson shoots Jeff and tells Buffalo Bill that he acted in self-defense.

The freed Dale rides into town to stop Steve, while Buffalo Bill forces the outlaws to reveal the identity of their leader.

After Steve, unaware of Dale's rescue, signs his property over to Simpson, Brave Eagle forces the sheriff to hand over Tom.

Buffalo Bill, Steve, and the sheriff's posse head to the Harrington Ranch and meet with the Indians and Tom.

Buffalo Bill convinces Brave Eagle to join forces with him to defeat the real killers.

Later, a grateful Steve, Dale, and Tom, having discovered that their land is actually rich in oil, bid Buffalo Bill a fond farewell.
