Ex-military investigator Jack Reacher is called in by James Barr, a man accused of a lethal sniper attack that leaves five people dead, and teams up with a young defense attorney to find an unseen enemy who is manipulating events.
When a man is killed by being thrown from a helicopter high over the California desert, loner Jack Reacher discovers that someone is targeting his old friends and teammates and launches a personal campaign to end the conspiracy before it claims any more lives.
