Death Sentence (2007)

With his beloved, high school hockey-star son murdered before his eyes as part of a gang initiation rite, the mild-mannered family man and successful insurance executive, Nick Hume, finds himself losing hope in the justice system. As a result, seething with revenge, Nick buys a long, double-barrelled 12-gauge Rossi Overland shotgun, and summons up the courage to start a war with the hardened criminal, Billy Darley, and his gang of street thugs. But, violence begets violence, and now, there is no turning back. And, one by one, Billy's henchmen are going to pay in blood. Will Nick be able to recognise himself when the bloodletting is over?—Nick Riganas
