After meeting Siriano in prison, Frank is tasked with uncovering what happened to Renaldo in order to destroy the organization he built. Frank quickly becomes ensnared in events that exceed his original mission.

Big cities can feel like small towns, and that is especially true for twins Jerilyn Kissee and Jeremy Hall. Jeremy can't seem to escape the town he grew up in, finding himself back home after bad luck at the Vegas poker tables. Jerilyn can't escape her dead-end job or her dead-beat husband Wayne. But when opportunity presents itself in the form of Deputy Tanner Brogdon, it does so with disastrous consequences that affect not only their lives, but Gabriella's, Frank's, and Kevin's in this explosive conclusion to the Tulsa Underworld Trilogy.
