WATCH OUT, GEORGE, HE'S GOT A SCREWDRIVER!
I can't say I'd ever heard of the original Les Rivières Pourpres, but having accidentally come across this précis of its sequel Crimson Rivers II: Angels of the Apocalypse I absolutely must let it lick my eyeballs:
As with the first movie, the pair's investigations intertwine and soon they are looking at a giant conspiracy involving a secretive group of monks on amphetamines led by Heinrich von Garten, played by Christopher Lee, searching for a treasure hidden by King Lothair II somewhere near the Maginot-Line.
