Does anyone have a copy of "Interzone"
I found this description of it and the last bit sounds like it certainly could be it. The name Swan rings a bell and I can see how a post apocalypse world might be mistaken for afghanistan.
http://www.imdb.com/title/tt0093268/http://www.badmovieplanet.com/inferno/archives/interzon.html"The first scene in the movie makes no sense. We meet our hero, Swan going to one of those after-the-apocalypse bars that happens to be in a cave. I'm not even going to elaborate. It was ridiculous, you couldn't understand what the people were saying and it really didn't help move the story along in any way. Well, then we meet the evil Mantis, a really buffed chick with an army of cutthroats and her partner Balzicon.(I'm not sure his name was Balzicon but thats what it sounded like) They happen to be attacking these monk like guys that protect the Interzone. Just so you'll know, the Interzone is the only habitable land left after the nuclear war. They don't explain that right away, I had to read the video box. The monk leader is injured after erecting a mental forcefield and before he dies he sends one of his men, Panasonic (!) to find Swan. Panasonic does find Swan. Together they free Tara, a slave girl, fight a fat guy and basically get captured by the bad guys. Swan's plan to defeat Mantis was to act like he wants to team up with her, betray Tara and Panasonic then free them. Then he and Tara go back to destroy Mantis' ammo supply and get caught. Mantis tortures them to death, but Panasonic comes to save them (too late) and uses his mental powers to resurrect Swan. This of course costs Panasonic his life. Tara is still dead at this point. Swan rushes to the Interzone and singlehandedly scares all of Mantis' soldiers away. (!)
Then he fights and kills Balzicon. Then he fights and kills Mantis. Then we learn that the great secret in the vault the monks were saving is all the knowledge and beautiful things that mankind has accomplished. (GASP)"
