Chuck Connors stars as the world champion rodeo cowboy Jim Sinclair, who had been hired by an English landowner, Commander Hayes, to bring modern ranching methods to his game ranch in Kenya. Sinclair was assisted by his Navajo blood brother John Henry and was "adopted" by an orphaned, ten-year-old Kikuyu native boy named Samson. The series was based on Ivan Tors' theatrical film Africa-Texas Style and was shot in Africa (for the backgrounds) and the Africa, U.S.A., park in southern California.
