Hap, a former '60s activist and self-proclaimed white trash rebel, and Leonard, a tough, black, gay Vietnam vet and Republican with an addiction to Dr. Pepper, are working a freelance surveillance job in East Texas. The uneventful stakeout is coming to an end when the pair witness a man abusing his dog, and Leonard takes matters into his own fists. One week later, a woman named Lilly Buckner drops by their new PI office with a proposition: find her missing granddaughter, or she'll turn in a video of Leonard beating the dog abuser. The pair agrees to take on the cold case and soon discover that the used car dealership where her granddaughter worked is actually a front for a prostitution ring. The mystery of her disappearance only deepens from there.
