Slow-motion stock footage and photographs of miners and their mines, with slow-motion color helicopter shots of their present-day locations, accompanied by slow-motion music. The movie doesn’t tell a conventional story, allowing you to apply your own knowledge and bias to the visuals. In my case what came to mind was Harlan County USA, Ace in the Hole and every Freakwater song (plus some Mekons/Freakons, Johnny Miner). Anyway, nothing hopeful or positive. The helicopter shots seem to back this up, showing these sites erased by history, covered up with parking lots, shopping centers and housing developments, unmourned. But it ends on a happy note, a massive parade of Durham-area miners marching into a cathedral.
Since each is under an hour, you could easily double-feature this with Coal Money, or maybe more appropriately, Profit Motive and the Whispering Wind.
