In hot and sultry Texas, Hack, an attorney and Korean War POW, is being pushed by his wife, his brother, and his so-called friends in the oil business to run for political office. But Hack would prefer to drink, look after his beloved horses, and represent the occasional long-shot pro bono case at his law firm. When Hack attempts to overturn a conviction for an old army buddy, he finds himself embroiled in the seamy underbelly of the Texas patronage system—and in the earliest beginnings of the United Farm Workers movement, led by a beautiful woman who speaks to his heart in a way no one else has. As Hack begins to bring justice to the underserved, he finds both a new love and a new purpose.
