When budding historian Donnie Ray Cuinn stumbles upon an old letter in the musty bowels of the Texas State Archives, he believes he has uncovered the true story of Sam Payne's valiant, or perhaps not so valiant capture of Mexican leader Santa Anna during the Battle of San Jacinto. Cuinn's findings are published in a local magazine. But the article eventually becomes fodder in the gubernatorial race between Democratic upstart Bob Braeswood and Republican favorite Sam Eben Payne V, the great-great-grandson of the Texas hero. Braeswood is intent on exploiting the past, while Payne will do anything to suppress it. In the ensuing battle, Donnie finds his beliefs, not to mention his relationships, stretched to the limit.
