Notorious serial killer the Upright Man has escaped from prison, and the FBI have no idea where to look for him. His brother, Ward Hopkins, suspects he may have been aided by the Straw Men, the shadowy organization founded on murder as a way of life that killed Ward's parents. But apart from his girlfriend Nina, a discredited FBI agent, the only other person who believes the Straw Men exist is John Zandt, a former homicide cop turned lone vigilante obsessed with tracking down the killers of his daughter, and now wanted for murder himself. Ward's brother was broken out for a reason. The Straw Men are planning something new and terrible. And only Ward, Nina and John stand against the Upright Man and his terrifying allies.
