Drifting through the Southwest with "Kentuck," his donkey companion, Daniel Brown stops in a town to get bullets to put down the wounded animal. Stopping in a gambling parlor, he is unjustly accused of murdering the proprietor, "Bull" Dunn. Dan escapes from the sheriff, steals a horse, jumps from the steed onto a train, and is hidden by a girl in her Pullman compartment. He later takes refuge with a prospector and learns that the girl who so generously helped him on the train owns a nearby ranch, which, unknown to her, holds rich gold deposits. Joe Walters, the ranch foreman, is plotting with Stella Dunn, the widow of the murdered gambler, to buy the girl's ranch for a pittance. With the help of the old prospector, Dan prevents the sale; and, when he is about to be arrested by the sheriff, the widow Dunn confesses to having murdered her husband.—AFI
