The Castaway Cowboy

On the island of Kauai, during the 1850's, a widow rancher Henrietta MacAvoy and her son, Booten, rescue Lincoln Costain from drowning. Lincoln is a Texas cowboy who has been shanghaied aboard a ship from which he elected to jump. Costain is persuaded to teach the Hawaiian farmhands how to become cowboys so that they can profit from the wild cattle on Henrietta's land. After apprehending a witch doctor, stopping a stampede and eliminating his business/romantic competition, Costain remains on the island to keep his new cowboys in line.
