In a heat-cracked border town, the bodies of nine illegal aliens - women and girls, killed execution-style - are unearthed in a shallow grave. Haunted by a past he can't shake and his own private demons, Hack attempts to untangle the grisly case, which may lead to more bloodshed. Domaged young Iraq vet Pete Flores, who saw too much before fleeing the crime scene, and his girlfriend, Vikki Gaddis, are running for their lives. Sorting through the lowlifes who are hunting down Pete, and with Preacher Jack Collins, a Godfearing serial killer for hire, in the mix, Hack is caught up in a terrifying race for survival - for Pete, Vikki, and himself.
