Steve and Tom are rivals for the hand of Mona. She prefers Steve; they become engaged and are later married. On the night of the wedding Tom in a jealous rage, is about to kill Steve, but changes his mind when he sees how slim his chances are to make a getaway. He decides, however, to waylay Steve the next day. He ambushes himself in the rocks above the trail that Steve is traveling, and, at an opportune time, fires three shots at his enemy. His shots all miss the mark, and Steve, turning quickly, sees Tom and fires back. Steve's bullet is fatal and Tom in falling drops his gun which becomes lodged in a crevice a hundred feet or so below the body. When Tom's body is found and no weapon discovered, Steve is convicted of having deliberately killed his former rival. He is sentenced to life imprisonment and the shock nearly kills his wife. She becomes very ill, and in her delirium sees a vivid picture of the shooting. In a state of somnambulism she walks to the spot where Tom's gun is hidden, recovers it and returns to the house. With this new evidence she manages to secure Steve's freedom.
