American actor/stuntman Jock O'Mahoney (aka Jock Mahoney) stars in the Australian The Kangaroo Kid. The star plays a 19th-century San Francisco detective named Tex Kinnane, who is sent "Down Under" to nab shyster lawyer Vincent Moller (Douglass Dumbrille). Several comparisons are made between the American Wild West and the equally treacherous Australian outback.
