Small town living fits Box simply fine. Blue collar, risk-free, simple. An interest for massacre keeps him in line at the regional abattoir where he has the chance to satiate his thirst for blood. When Nathan, a young parolee arrives around, Box is instructed to take him under his wing, as well as soon the two men bond over a bloody murder. Incapable to withstand the temptations of blood, the two create a relationship revolving around their sickness for power. A friendship which misbehaves news for everyone in the area as they come to be lambs for the slaughter used entirely as amusement for the duo.
