In Tucson, Det. John Dorer and his team investigate the gruesome murder of a 58-year-old woman found naked and dead under a highway overpass--a satanic symbol near the body is written in blood. When detectives learn about a similar case, they believe they may have a serial killer on their hands and quickly enlist the help of the entire Tucson PD to track down the killer before he strikes again. And in Birmingham, a community lives in fear after a teenager is senselessly shot in his apartment complex. Det. Eric Torrence and his team head out to the victim's neighborhood to help convince witnesses to speak, so they can bring the killer to justice and put the community back at ease.
