Nan comes west to keep house for her brother. She is considered, out in the land of cactus and sand, a mere child when it comes to the real nerve that is required out in that country. But Nan thinks otherwise. One day she and her brother go for a ride in their motor car and the machine breaks down as they near a hut. The brother nays that he will go to get aid and tells Nan that she better look out for a bandit that has been terrorizing the county. Nan enters the cabin and finds that it is the home of the bandit. She is frightened when the man himself comes in masked. A struggle follows when the man says that he will kill her; she rebels and gets hold of his gun. When he still persists she fires and he falls as though dead. She is frightened at what she has done and calls for help. Then her brother, who is the bandit in disguise, gets up and tells how the whole thing was to test her nerve and how he removed the bullets from the gun beforehand. Nan has proved her nerve.
