A rogue IRS agent leads a raid on the wrong house and destroys Finn O'Casey's world. A sympathetic neighbor, the leader of organized crime, is not what he seems to be. Both men thought O'Casey was a mild-mannered accountant. They thought wrong. O'Casey, a former member of an elite special operations unit, goes dark and rejoins his former colleagues, promising vengeance on those responsible.

To escape the vengeful O'Casey, the agent tries to frame him for the murder of another IRS agent. Local, state, and federal law enforcement officials quickly accept O'Casey as the prime suspect. But the FBI's lead investigator, a young Native American woman named Marcie Billie, isn't convinced the CPA is the killer. She begins to suspect the rogue agent.

Moral: Pick your victim carefully.
