Theodore Roosevelt must fend off a powerful neighbor, the Marquis de Morés, who is intent on seizing Roosevelt’s newly built Elkhorn Ranch in an underhanded land grab. To save his ranch, Roosevelt travels to the home of the Marquis and his beguiling wife, Medora, who is just as cunning as her husband. Back at Elkhorn, Roosevelt’s new ranch hands, former lumberjacks Bill Sewall and Wilmot Dow, are attempting to master the saddle when their bronc-busting lessons are suddenly cut short by the arrival of the Marquis’ henchmen. For one long night, Elkhorn’s very survival hangs precariously in the balance.
