Western starring James Stewart and Maureen O'Hara, based on real-life events that took place in the 1880s when Hereford cattle were first introduced to the American West. Martha Price (O'Hara) and her daughter Hilary (Juliet Mills) enlist the help of Sam 'Bulldog' Burnett (Stewart), a wandering ranch hand, to carry out the dream of Martha's late husband who died en route to America. His dream was to introduce Hereford cattle by transporting a lone bull, Vindicator, to Texas to breed it with longhorn cattle. Martha, Hilary and Sam set out on the road to Texas with the bull, but the trail is fraught with dangers and Sam has to rescue the women from a series of Western-style ambushes and abductions.
