An epic examination of the American dream, played out on the spacious, mythic Texas landscape. The story charts Texas’s evolution from ranching state to oil capital. In addition, the film explores issues of race relations. A young cattle baron marries a well-bred Maryland beauty and transplants her to a rustic ranch. The new bride, Leslie Benedict, quickly learns about the divisions between the Americans and the Mexicans, between the privileged and the poor. Her husband retains these prejudices even when his son marries a Mexican-American nurse. Leslie also must contend with a ranchhand who loves her from afar, and who despises her husband's wealth. When the ranchhand strikes oil and also becomes rich, he still fails to win either Leslie or the town's respect.
