Based on a even more gruesome crime spree that began almost a decade ago, the movie Blind Shaft is a must-see dark satire about two cons who kill hapless migrant works in order to extort the similarly unscrupulous owners of illegal coal mines. The dialogue is smooth yet blunt. An unforgettable scene shows the cons being schooled by hostesses at a karaoke bar on the new, jaded lyrics to a communist anthem.
