Spider Head Prison "tells the story of a talented and visionary advanced prison where prisoners wear a device connected by surgery to inject a certain dose of mind-altering drugs in exchange for a reduced sentence. There are no bars, no cells, and no orange prison uniforms. In Spider Head, incarcerated volunteers are free to be themselves until they lose themselves. When two experimental subjects establish a friendship, their road to redemption is full of ups and downs, as the experiment begins to completely break through the limits of free will.
