No Escape (1994)
The film is a very loose adaptation of the 1987 novel "The Penal Colony" by Richard Herley. The movie has been compaired to Robert A. Heinlein's short story "Coventry", "Escape from New York" (1981) and its sequel "Escape from L.A." (1996)the TV movie called "New Eden" (1994) along with "Fortress", "Papillon", "Blood Camp Thatcher".
Sure it is a futuristic prison movie but the warring camps and the anti-social anti-hero mostly bring to mind "The Road Warrior" (1981) without the cars. Alzur
The year's 2022 and prisons have turned into private companies without government interference. Absolom is the name of a prison colony island where the sadistic warden (Michael Lerner) plays off the Outsiders against the Insiders. The former are an unorganized bunch of savages wearing masks and hunting with primitive weapons, led by the relentless but charismatic Walter Marek. The Insiders, however, attempted to found a peaceful community where they grow crops and seek for moral redemption. The newly arrived and military trained prisoner Robbins would make a great asset for the Insiders, since he's the only one to have ever escaped from the Outsiders, but he's stubborn and anti-social and solely intends to get off the island alone.
