You gotta help me figure out a movie title; driving me crazy [View All]

It was one of those bad post-apocalpytic type movies, sort of Mad maxish but without the production values, set in a post-Atomic (I think) America (or perhaps some other country) with lots of outdoors and busted buildings and guns and stuff.

There were also nuns.

And the title had the year in it - like 2002, or 2200, or 2210, sonme four digit number, and I think the title also includes the word "nun", but I can't be certain on that. And the title also had a word equating with death: maybe death, or kill, or massacre, or rape, or something terrible word like that.

I did an IMDB serach on "nun" and after looking at a few hundred titles, and knowing there were thousands more to go, I gave up.

Any idea what movie I'm talking about?
