A killer strikes under cover of darkness, triggers no alarms, and leaves no evidence behind. Detective Alex Cross is on the hunt of a killer who is targeting entire families around Washington, DC. But Cross isn't the only one investigating - a charismatic true-crime author has spotted patterns in the case of 'The Family Man' killer that others have missed.

It's up to Cross to determine whether the writer's theories are fact or fiction - before another family falls victim.
