Caleb Landry Jones takes the title role, a boy nicknamed ‘Nitram’ because his real name is Martin and the community thinks he’s ‘backward’. He’s a selfish, violent young man whom his parents love but can’t control and who, somehow, ends up with a deranged lottery heiress. Nothing about his life is normal, but red flags about his erratic behaviour go unheeded. Could he have been stopped? Nitram always appeared profoundly troubled, but Australia’s lax gun laws made him a murderer.
