A Real American Hero (1978) on Netflix

Plot summary

In 1967, Buford Pusser wears the sheriff's star in a Tennessee county. Poisoned moonshine reaches the area's teenagers, and two boys die while two girls are blinded for life. The liquor came from the county's king of bootleg alcohol and drugs, and Pusser decides to go after the man who supplied it. Reaching him means bending the law, because the rules Pusser works under will not stretch as far as the case demands. His county also hands him a fight with a former friend, and with a group of women who lean on a blue law to keep a freed prostitute away from the town. Pusser is drawn from a real-life Tennessee lawman whose career inspired the Walking Tall movies.
