Lone Star (1996) on Netflix

Sam Deeds is the Sheriff of Rio County, TX and to some extent, he lives in the shadow of his late father, the venerated former sheriff, Buddy Deeds. Sam had always had a difficult relationship with his father, especially during his teenage years when Buddy absolutely forbade him to see a pretty Hispanic girl, Pilar Cruz. Local mythology has Buddy Deeds, when only a sheriff's deputy, murdering the corrupt and violent sheriff of the day, Charlie Wade. When Wade's remains are found in the desert, Sam finds himself investigating his father and slowly peels away at the story from the perspective of its long-term residents including a local bar owner, Pilar's mother and the current mayor. What Sam learns shows his father in a different light and has a direct impact on his own life choices.
