Videodrome (1983)

First it controlled her mind, then it destroyed her body... Long live the new flesh!

The morally questionable hero of the tale is one Max Renn, a television executive searching for an intense new program for his sex-oriented network. He ultimately discovers an underground program called "Videodrome," which appears to broadcast pornographic snuff films of actual murders. Horrified but perversely intrigued, Renn sets out to find the truth behind the program.
