Det. Roland March is a homicide cop on his way out. But when he's the only one at a crime scene to find evidence of a missing female victim, he's given one last chance to prove himself. Before he can crack the case, he's transferred to a new one that has grabbed the spotlight--the disappearance of a famous Houston evangelist's teen daughter. 

With the help of a youth pastor with a guilty conscience who navigates the world of church and faith, March is determined to find the missing girls while proving he's still one of Houston's best detectives.
