Hannah Lee (Abigail Breslin) is a bright teen girl trapped in the dark Southern underworld of violence and guns, drugs and vicious biker gangs. Neglected by her angry sister Amber (Alexa Vega), her only refuge is her troubled uncle Donny, who is a drug addict. Both live in fear of "Uncle Frank" Stinson (Sean Bean), who runs the illegal family business with an iron fist, aided by his psychotic brother Bobby.

When Amber falls in love with family rival Wild Bill (James Purefoy), Hannah realizes there is no escape from her ruthless uncle and cleverly schemes to pit one pawn against another in a cunning game of revenge.
