In Australia, the divorced father Christian Forteski grieves over the death of his beloved daughter Jesse that was found dead intoxicated with heroin and cocaine and also with the semen of four men. When he anonymously receives a video tape by mail with an adult movie of gang bang where his beloved daughter is the lead star, Christian drives through the outback of Australia with a toolbox chasing the producer, director, cast and crew of the film, in a violent journey of revenge, and finds a network of drugs and pornography. Meanwhile he gives a ride to the eighteen year-old runaway Alice that is pregnant and he feels empathy for the girl. He befriends Alice but does not disclose the truth about his "business trip". When Christian and Alice are abducted by the most violent gangster, Derek, Alice experiences what Jesse had lived before dying for the despair of Christian.
