Stalker (1979)

“There's no need to speak. You must only...concentrate and recall all your past life. When a man thinks of the past, he becomes kinder.”

Near a gray and unnamed city is the Zone, a place guarded by barbed wire and soldiers, and where the normal laws of physics are victim to frequent anomalies. A stalker guides two men into the Zone, specifically to an area in which deep-seated desires are granted.
