Colonial Australia. Dick and Jim Marston are summoned one night to meet their father Ben, an Englishman convicted of armed robbery and transported to New South Wales. When the brothers reach Terrible Hollow, a huge, natural hideout, they are reunited with their father and also introduced to his leader, the charming, infamous bushranger Captain Starlight. Dick and Jim are needed to help drive 1200 cattle through 1000 miles of near desert. The herd, of course, is stolen.
