Inspired in part by Sydney nurse Anita Cobby, who was gang raped, tortured and murdered by five men who kidnapped her as she waited for a bus to take her home late one night, The Boys takes the viewer into the world of a violent and dysfunctional family controlled by the intelligent, malevolent, violent, and manipulative eldest son.

After being released from a twelve-month prison sentence, Brett Sprague returns to his mother's suburban Sydney home and the tension within the family rises almost immediately. His mother tries to keep the peace, only to see her three sons turn on her new boyfriend. The narrative climaxes when after eighteen hours of drinking and fighting, the boys go out and cruise the streets, looking for trouble. It is then that they see a girl waiting for a bus on her own.
