A murder mystery set in the segregated town of Dodge County, Texas in 1954. Swift Justice will appeal to fans of the movie Mississippi Burning and John Grisham's book, A Time to Kill, and tells the story of Leon Brooks, an educated black man, who comes under the wrath of the Texas KKK for initiating a voting drive.

The Klan, which is led by the Imperial Wizard Atwood Baker, who is called "Judge" because he is the Chief Justice of the Texas Supreme Court, cannot allow the voting drive to happen. His solution - lynch Leon Brooks and set an example.

But a mysterious person, who is disguised, comes to Leon's aide as the noose was around Leon's head. Leon can't tell whether the person is black or white. The person leaves as quickly as he or she arrived.

Within four days, numerous white people are murdered, and the Klan has no idea who's doing it. Sheriff Jefferson Mason, a tall, heavy-set man in his 50s and a local leader in the Klan as well, investigates the crime. The Klan's revised solution - kill more Negros and set the town on fire.

FBI Special Agent Roger Perry and his partner, Tom Hall, rush to Dodge County to solve the murders and bring down the Klan. The murders and racial tensions also bring in the national media. Dodge County is in disarray. Will it ever be the same? Will the people responsible for the crimes be brought to swift justice?
