Into the Texas Panhandle of the late 1880s, America's last great open range, ride two young cowboys: Nate Reynolds, the scion of a well-to-do family, in search of adventure and gold; and Billy Champion, a ne'er-do-well with a stubborn streak and an eye for the ladies. Together they aim to rid this violent territory of rustlers, horse thieves, and the rest of the devils. But when the friends fall for the same green-eyed beauty, their brotherhood will be put to the test.
