Betrayal in Blue follows the return of Zachary Blake and Jack Dylan as they fight law enforcement itself in picturesque Manistee, Michigan. Following its triumph over white supremacists in the field and in the courtroom, law enforcement in Dearborn, Michigan have enjoyed the relative tranquility. Unfortunately, not for long, as a second (and more dangerous) syndicate and its leader plot revenge for their fallen brothers. Police Captain Jack Dylan and his team are dedicated to thwarting a sarin gas attack until the FBI usurps the investigation. When the terrorist group's leader evades the FBI's dragnet, Jack goes rogue and hunts him down. The inevitable standoff finds Dylan alone with his nemesis in an unfamiliar city with no FBI or local law enforcement to support him. His plans go awry, and Jack finds himself arrested by local authorities and placed on trial for his actions. Attorney Zachary Blake comes to his defense in the biggest trial this quiet community has ever seen. The local cops and the FBI think they have a winner, but Zack and his lead investigator, Micah Love, believe there’s more to the story than meets the eye.
