Wayne entered the service when Chris was given the option of military duty in lieu of prison as the result of an earlier episode with the law.
Driving through Louisiana, the brothers pick up hitchhiker Jenny Scott (Cheryl Waters), a pretty blond with a shady backstory that she would rather not discuss.
Meanwhile, local backwater town sheriff Reed Morgan (Baer) is preparing to bring his son Luke (Leif Garrett) home from military school.
Unable to repair the car themselves, they scrape together enough money to get it patched up by garage owner Hamp (Geoffrey Lewis).
Inside the house, Morgan's wife is brutally raped and murdered by two men who then kill a cop when pulled over.
When Morgan returns home to find his wife dead, he pursues Chris, Wayne and Jenny, believing they must have been responsible.
In each case, most, if not all, of what was portrayed on screen was fictional (with the exception of The Town That Dreaded Sundown, which was inspired by the Texarkana Moonlight Murders of 1946).
The Anchor Bay DVD release included an audio commentary with director Richard Compton and the featurette, Macon County Line – 25 Years Down the Road.
