In the American Southwest, in 1930, Trude Mason and his mother ride out into the predawn quiet, hoping to escape Trude's brutal, violent father and an equally violent past. They plan on reaching Colorado, a place they believe holds the biggest ranches, the most limitless promise, and lives of the greatest ease. What Trude finds in a small border town in New Mexico, however, is brutality and lawlessness in the form of a cruel, pitiless sheriff and his devoted posse. When they arrest and sentence to death a young woman whose life Trude has saved, he must endure an explosive collision between conscience and self-preservation.
