In the poor Adelaide suburb of Salisbury North, 16-year-old Jamie lives with his distressed mother, Elizabeth Harvey, and his brothers — including Troy, who rapes Jamie. One day, his mother's boyfriend takes Child pornography. When the police are reluctant to intervene, Elizabeth is contacted by Barry, a gay cross-dressing man who introduces her to John. John, who despises Pedophilia and Homosexuality, continually harasses the boyfriend via means such as throwing kangaroo's blood and body parts at his house until he moves away. John begins to assume the role of Jamie's father figure. Barry tells John the names and addresses of paedophiles in the area, and John creates a wall with pictures and details about each, including notes saying things like "I'm coming for you".
