Detective Scott Priest had never considered himself to be anything more than a hard-nosed, hardworking cop who did his best to uphold the Priest lineage of hard-nosed, hardworking cops. But that simple notion is about to be put to the ultimate test. The Denver Police Department is in turmoil after two of its own are gunned-down by a fellow officer. The motives for the shooting are unclear, but speculation mounts that a criminal element within the department is responsible. As he struggles through a grisly murder case involving a hotel room attendant, Detective Priest will also find himself on the front lines of a secret investigation into members of his own unit - men he once trusted with his life. Before it is all over, he will question whether or not there is anything left to trust, including the Priest family lineage itself. It is a battle that he never could have dreamed of waging. And it's only just begun.
