Law Professor, Michael Riley's life has shrunk to a pin prick. Wake up. Go to work. Repeat. So when he goes for his usual morning jog, he's not expecting to stumble onto a man mutilating a corpse and then killing his partner with a shovel. Riley takes off running the opposite way and hides until he can call the police to report the gruesome crimes.
But from the beginning Riley sees this isn't a case for police. The FBI take control of the scene, leading him to realize something bigger is at work. The man who committed the crimes isn't just any murderer. He goes by the name Isaac and he's working in league with a domestic terrorist organization that can bring the government to its knees. Using a letter from Lincoln as smokescreen, Isaac and his conspirator Samuel, lineup the targets and execute the missions.
Isaac knows that Riley witnessed the initial murder but Riley has seen more than he knows. His morning jog set of a chain reaction as Isaac and his own government race to stop Riley before he can uncover the truth. No matter how many times the FBI orders Riley to stay away from the investigation, he can't walk away - not when the next dead body could be his.
