In 1979 a movie Hardcore came out that was about a father searching for and rescuing his teenaged runaway daughter. She gets involved in the porn industry with some very bad people who a rumored to be making snuff films.

In todays world of the internet there is access to anything at all if the price is right. From rape to torture, and even murder and you can direct the action.... These people need to be rooted out and killed, the customers AND the providers.
