In New Orleans, Texas Ranger John Q is out of his jurisdiction, and possibly out of his depth. It seems everyone in Louisiana wants to send him home, and every time he asks questions there's trouble: from the pharmacist to the detective running scared to the pimp who turned to him as a last resort.
Ranger John Quarrie is called to the scene of an apparent suicide by a fellow war veteran. Although the local police want the case shut down, John Q is convinced that events aren't quite so straightforward. When his hunch is backed up by the man's son, Isaac - just back from Vietnam, and convinced his father was murdered - they start to look into a series of other violent incidents in the area, including a recent fire at the local Trinity Asylum and the disappearance of Isaac's twin brother, Ishmael. In a desperate race against time, John Q has to try and unravel the dark secrets at the heart of this family and get to the truth before the count is up
