Small town living suits Box just fine. Blue collar, safe, simple. A passion for slaughter keeps him in line at the local abattoir where he has the chance to quench his thirst for blood. When Nathan, a young parolee arrives in town, Box is instructed to take him under his wing, and soon the two men bond over a bloody murder. Unable to resist the temptations of blood, the two form a friendship revolving around their sickness for power. A friendship which is bad news for everyone in town as they become lambs for the slaughter used solely as entertainment for the duo.
In 1825, Clare, a 21-year-old Irish convict, chases a British soldier through the rugged Tasmanian wilderness, bent on revenge for a terrible act of violence he committed against her family. She enlists the services of an Aboriginal tracker who is also marked by trauma from his own violence-filled past.
