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.
This is by Jean-Michel Folon for the French release of the film.
Thank you for the additional context! This film has had a lot of unique posters for different releases and I think most of them would fit this community.
