Ray Baldwin bids his young bride, Ethel, goodbye and leaves. In their cabin, Ethel is shown looking at the portrait of a small boy. On the back of the portrait is an inscription to the effect that the boy is her brother, that he was stolen by the Indians when but a child and that a prominent scar on his hand is the only mark by which he might be recognized. Rattler Joe is a notorious bandit in the county of which Baldwin is sheriff. Joe goes to the Baldwin cabin during Ray's absence. Ethel by a ruse shoves him into a small closet and locks the door. She tries to escape as Joe starts breaking down the door and his left arm comes through the panel. Ethel seizes an ax and is about to strike when a scar on the bandit's arm catches her eye. She recognizes it as that of her brother: she brings him from the closet and shows him the picture. Ray returns home. He sees them through a window. Joe is about to shoot when Ethel stops him with the information that Ray is her husband. Joe escapes. Ray enters and bitterly accuses his wife and then leaves. Later, Baldwin pursues Joe into the hills. By an ambush Joe captures Baldwin. They are attacked by Indians and both of Joe's arms are shot. Baldwin takes him to his cabin and his wife, where he learns the truth; that the bandit is the brother of his wife.
