Susan Allenby's (Enid Markey) father is killed during a robbery staged by Bannack's corrupt sheriff Tom Slade and his men, leaving her to care for her eight brothers and sisters. Andy Crawford and his father William take the orphans in, but after Andy's father is killed, the young prospector vows to avenge his death and clean up the town. Learning that Slade's deputy, Ned Skinner, is his father's murderer, Andy orders his arrest, but Slade ignores Andy, who finally kills Skinner in a duel. While Andy's vigilante committee is searching for the outlaws who held up the stage, Slade imprisons Susan in the saloon. Informed of the kidnapping by the children, Andy returns and rescues her, killing Slade in the process. The appreciative townspeople then name Andy the new sheriff, and Susan happily agrees to become his wife.—Pamela Short
