It's January 1969 in the small rural community of Center Springs, Texas. Constable Ned Parker suspects a larger mystery behind the seemingly accidental death of his nephew, R .B., who was found in his overturned pickup near Sanders Creek bridge. It appears that R. B. drowned in the shallow water, but something doesn't add up for Ned, who begins turning over stones in search of what really happened the night R. B. died.
The mystery leads Ned to the Starlite Club, a dangerous honky-tonk recently constructed in a no-man's land on the Lone Star side of the Red River. His investigations there uncover suspicious characters, drugs, and gambling, but even more troubling are a series of murders that seem designed to eliminate anyone who might know what really happened to R. B. on that cold January night.
As he works his way through the cover-up, Ned lands himself in a high-stakes game of consequences with no good end in sight. Are the good citizens of Center Springs conspiring against Constable Parker in his search for the truth?
